Structure and energy spectrum of negative ions in non-polar liquids

Proceedings of 2002 IEEE 14th International Conference on Dielectric Liquids. ICDL 2002 (Cat. No.02CH37319), 2002

The electron photodetachment energy from a negative ion increases significantly inside a nonpolar liquid in comparison with its value in the vacuum. It is customary to consider that it is a result of the polarization interaction of the ion with the atoms or molecules of the liquid. However, the exchange interaction of the outer electron of the negative ion with ...

  • Structure and energy spectrum of negative ions in non-polar liquids

    The electron photodetachment energy from a negative ion increases significantly inside a nonpolar liquid in comparison with its value in the vacuum. It is customary to consider that it is a result of the polarization interaction of the ion with the atoms or molecules of the liquid. However, the exchange interaction of the outer electron of the negative ion with the electrons of the external atomic shells of the neutrals also plays an important role. This interaction may result in the creation of voids or bubbles around the negative ions which are similar to the electron bubbles in liquid helium and some other liquids. The electron binding energy of negative ions of different atoms and molecules injected in liquid rare gases and some hydrocarbons is calculated with taking into account of the quantum nature of the outer electron state and the possibility of the creation of a void near the ion.

  • First-Principles Study of Magnetic Exchange Interactions of $3{\rm -D}$ Transition Mental Adatoms on Graphene

    We have performed first-principles calculation to investigate the magnetic exchange interactions of 3-D transition metals (TMs) adatoms on graphene. Our study found that the most stable adsorption sites and geometries of different 3-D TM dimmer adatoms on graphene are obviously distinct. The obtained magnetic exchange energies indicate that Fe and Co adatoms on graphenes are always ferromagnetic coupling. Thus, they may be a candidate of graphene-based spintronics devices. Furthermore, electronic structure analysis shows that mechanism of ferromagnetic interaction of 3-D TMs adatoms on graphene is either direct exchange (two TMs adatoms are on the same side of graphene) or superexchange (two TMs adatoms are on the two sides of graphene).

  • The Effects of Surface Coating on the Structural and Magnetic Properties of CoAg Core-Shell Nanoparticles

    We have investigated the impact of Ag surface coating on the microstructure of CoAg core-shell nanoparticles, and the consequences for the magnetic properties. Atomic structures were simulated using a molecular dynamics approach utilizing the embedded atom method. The magnetic properties were then simulated using an atomistic approach using a classical spin Hamiltonian, taking into account the long-range nature, atomic separation and directional and phase dependence of the exchange interactions in Co. For pure cobalt nanoparticles with a diameter less than approximately 3 nm the internal crystal structure showed multiple twinned regions and the morphology of an icosahedron. The addition of a monolayer silver coating alters the internal cobalt crystal structure to a regular planar form along the cubic [111] direction with a mixture of face centred cubic (fcc) and hexagonal close packed (hcp) atomic arrangements. The local atomic environment was used to assign anisotropies to the atoms on a site by site basis. Moreover, the capping layer influences the shape of the particle and yielded a morphology similar to that of a truncated octahedron. Taking into account the effects of surface anisotropy in addition gives an overall picture of anisotropy for CoAg nanoparticles. We present the results of calculations estimating the energy barrier to magnetization reversal and the intrinsic coercivity for these particles

  • Faraday rotation in Fe-based semimagnetic semiconductors

    The dependence of Faraday rotation (FR) of the light polarization phase on the radiation wavelength, the temperature, and the magnetic field for Fe-doped crystals of CdTe and CdSe is investigated. The Faraday effect enhancement due to s,p-d exchange interaction is found for Fe-doped SMS (semimagnetic semiconductors). The variation of s,p-d exchange interaction constants estimated for CdTe:Fe samples corresponds to the values known for Mn- containing SMS. Along with a steep drop of the oscillator strength, exciton transition as a consequence of Fe impurity introduction causes a substantial decrease of the Faraday effect amplifying degree in such materials. This phenomenon and the insufficient solubility of Fe-atoms in CdTe and CdSe lattices make the realization of applied aspects of SMS difficult.<<ETX>>

  • Active supercurrent control in superconductor/ferromagnet heterostructures

    Several recent papers predict that the critical temperature of superconducting/ferromagnet heterostructure can be controlled by varying the exchange field of the ferromagnet within the superconductor, providing a means of controlling the superconducting properties. This paper reports the first experimental observation of this effect: we show that the critical temperature and critical current of a Nb/Co bilayer can be controlled by a small magnetic field, on the order of a few tens of kA/m. In these devices, the suppression of T/sub c/ is minimised at the coercive field of the Co layer implying that with a sufficiently fine domain structure the net exchange field in the superconductor is reduced. These structures offer the potential for active control of the superconducting properties in both low and high T/sub c/ materials through the application of very small magnetic fields.

  • Micro Magnetic Exchange Interaction Tensor and Magnetization Reversal of${\rm L}1_{0}$FePt Based Alloy Thin Film Nano-Structures

    We investigate the effect of crystal symmetry driven tensor form of micromagnetic exchange stiffness A on switching properties of L10FePt composite nano-structures. The exchange interaction term in micromagnetic energy functional have been constructed to capture the results of the first principle calculations for magnetic excitations in [001] and [100] directions. We find that out-of-plane (OP) exchange component (A||) is about two times weaker as compared to the in-plane (IP) component (A⊥). We study the effect of this difference between principal axis elements of A tensor on the M-H loops using micromagnetic simulations. We compare two cases for IP and OP exchange constants: (a) A⊥= A||(limited case) and (b) A⊥= 0.5 A||(based on ab-initio calculations), and find that the a thermal coercive force for 30 × 30 nm bi- layer rectangular dots differs for these two cases. Further, we find that the coercive force difference between two cases decreases as the external field goes from OP to IP.

  • On the anisotropy of the exchange interactions in the rare earth orthoferrites

    This paper presents some new results on orthoferrite magnetic properties. We have measured the temperature dependence of the spontaneous magnetization for neodim, samarium, and thulium orthoferrites having compensation temperatures. The measurement of the magnetic permeabilities near these temperatures makes it possible to find the effective fields of exchange interactions between the iron and rare earth ions and to prove that these interactions have strong anisotropy. For example, the exchange interactions for TuFeO<inf>3</inf>have opposite signs along the<tex>a</tex>and<tex>c</tex>axes, so that the spin reorientation results in the change of the orthoferrite spontaneous magnetization. The different mechanisms of the anisotropy of the iron and rare earth ion exchange interactions are discussed.

  • Magnetic relaxations in metallic films single and multilayer structures

    Summary form only given. The intrinsic magnetic relaxations in metallic films will be reviewed. The intrinsic relaxation in magnetic metals is different from that in magnetic insulators. The intrinsic damping mechanism in metals is caused by incoherent scattering of itinerant electron-hole pair excitations by phonons and magnons. The electronhole pair excitations are either accompanied by a spin flip or the spin remain unchanged. It will be shown that the electron spin flip excitations can be caused by the exchange interaction between magnons and itinerant electrons (s-d exchange interaction), and they can lead to magnetic relaxation when the spin orbit interaction is included which provides a spin flip relaxation of itinerant electron-hole pairs.

  • Nucleation fields and grain boundaries in hard magnetic materials

    Numerical micromagnetic calculations of the nucleation field of two- dimensional magnetic microstructures reveal the effects of interparticle interactions on the magnetization reversal mechanism. The results show that the magnetic behavior of interacting particles drastically changes with the grain size. For an average grain diameter D>100 nm, the particles of magnetic microstructures are strongly coupled by long range magnetostatic interactions. Therefore, the reduced nucleation field of misoriented grains determines the coercive field of large grained particle ensembles irrespective of the grain boundary type. In smaller grains long-range demagnetizing fields become less effective. Nonmagnetic boundary phases prevent the expansion of a reversed domain nucleus into the neighboring grains. If the average grain diameter approaches the domain wall width, short-range exchange interactions between neighboring grains increase the nucleation field.<<ETX>>
