  • Ocean mining - 1985

    Several reasons for the continuing reduction of activity in ocean mining are presented in the historic context of the 1965 to 1980 governmental, academic and industrial programs. The causes are identified as primarily economic with uncertainties raised by the Law of the Sea Treaty debate and political indecisiveness contributing to restriction of private sector investment. Revitalization of ocean mining is shown to depend upon the jettisoning of the outer Continental Shelf Lands Act, the development of a strong exploration data base by Government programs and sponsored research, and the marked improvement of the free world metals market. The inevitability of the eventual development of marine hard minerals is emphasized.

    Magnetic annealing kinetics for the induced anisotropy and the coercive field in amorphous alloys Co58Ni10Fe5Si11B16were studied. Spectra of activation energies for "reversible" and "irreversible" annealing processes are determined and discussed in the light of a micromagnetic theory of the induced anisotropy recently proposed [1] on the basis of the thermodynamics of two- level systems [2] : 1. The formation of induced anisotropies in Co58- Ni10Fe5Si11B16is attributed to an atom pair ordering process around free volumes. 2. "Reversible" annealing processes are characterized by a spectrum of activation energies ranging from 1.8 eV to 2.3 eV. The small pre- exponential factor of τo,R = 6.10-16s points to a localized atomic, thermally activated process. 3. "Irreversible" annealing processes are characterized by small activation energies ranging from 0.5 eV to 1.0 eV. The large pre- exponential factor τo, A = 3-10-4s points to a long-range migration of free volumes leading to an immobilization of atom pairs.

  • Electrodeposition of Cobalt Nanoparticles on Thin Niobium Films

    Hydrogen evolution reaction (HER) takes place immediately after the reduction of Co nanoparticles (NPs) and varies the structure of the Co NPs. The Co NPs deposited by low cathodic current exhibit their hcp- 〈1011〉 parallels the surface normal. To increase the cathodic current can increase the ratio of the polar magnetization to the longitudinal one. This is referred to an increasing population density of the Co NPs which have hcp(0002) structure during the very early depositing stage. However, for further deposition, the intensive HER in such a high cathodic current could vary the shape of the Co nanoparticles. In order to make the Co NPs to persist their hcp(0002) structure, a double pulse current technique was chosen. The population density of the Co NPs is significantly controlled by the first high current pulse and the ratio is obviously increased. This implies that the HER effect plays an important role in the initial nucleation structure of the Co NPs. This provides us a method to control the structure and magnetism of the Co NPs by choosing a suitable combination of current pulses.

  • Cylindrical domains in small ferromagnetic spheres with cubic anisotropy

    Magnetization configurations are computed for small ferromagnetic spheres with cubic anisotropy. A cylindrically symmetrical configuration is found, which has a lower energy than a single domain, for a sphere radius larger than about 27.7 nm, for cubic cobalt. In magnetite, the changeover from a single domain to the cylindrical configuration is at a radius of about 27.0 nm. This problem has been studied particularly for cubic iron oxides, used in magnetic recording.<<ETX>>

  • High coercivity Zr and Co substituted (Nd-Pr)-Fe-B nanophase hard magnetic alloys

    The effects of Zr and Co substitutions for Fe on the magnetic properties of nanocrystalline near-stoichiometric (Nd/sub 0.75/Pr/sub 0.25/)/sub 12/(Fe/sub 1-x/Co/sub x/)/sub 82-z/Zr/sub z/B/sub 6/ (x=0,0.1,0.2 and z=0-4) alloy ribbons are reported. The nanoscale structures were derived by devitrification annealing of amorphous as-cast ribbon. Very good combinations of energy product, (BH)/sub max/ (/spl sim/160 kJ/m/sup 3/) and intrinsic coercivities, /sub i/H/sub c/ (within the range 800-1400 kA/m for various Zr concentrations) were achieved for the Co-free alloys although the Zr addition resulted in some reduction in T/sub c/. For alloys in which, also, 10 and 20% of the Fe was substituted by Co, excellent remanence enhancement, J/sub r/ (to >1 T) were achieved with 1 at% Zr addition. Combined with excellent squareness of the J-H second quadrant, this gave (BH)/sub max/ up to 175 kJ/m/sup 3/, together with Curie temperatures, T/sub c/ of >375/spl deg/C and >460/spl deg/C for 10 and 20% Co, respectively, and with only minor reductions in /sub i/H/sub c/. The role of Zr in promoting uniform and refined grain structures and enhancing the magnetic properties will be discussed.

  • 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
