Magnetization reversal

View this topic in
Magnetization reversal, or switching, represents the process that leads to a 180° reorientation of the magnetization vector with respect to its initial direction, from one stable orientation to the opposite one. Technologically, this is one of the most important processes in magnetism that is linked to the magnetic data storage process such as currently used in hard disk drives [1 1]. (Wikipedia.org)

It is shown that, with applied field rise times longer than 1 ns, the ripple can be expected to relax in equilibrium with the rotating means magnetization. Magnetostatic stray fields prevent blocking from strongly affecting the rotational process and permit a stable ...

Extraction of blocking temperature distribution from zero-field-cooled and field-cooled magnetization curves

IEEE Transactions on Magnetics, 2005

Superparamagnetic fluctuation of magnetic nanoparticles is studied. We examine the validity of the simplified approach using the difference between zero- field-cooled magnetization and field-cooled one. The results show that it is valuable for estimating the blocking temperature distribution of polydispersive particles even in magnetic fields, if both surface effects and inter-particle interactions are negligible.

  • Magnetic Behavior of Ni/Cu Multilayer Nanowire Arrays Studied by First-Order Reversal Curve Diagrams

    Arrays of Ni/Cu multilayer nanowires were fabricated by electrodeposition into alumina templates (pore diameter = 175 nm, interpore distance = 300 nm), with an Ni disc thickness between 20 and 50 nm, and a Cu thickness between 10 and 35 nm. Vector major hysteresis loops were measured with an out-of-plane (along the nanowire axis) and inplane (perpendicular to the nanowire axis) applied field. During the magnetization reversal, we did not observe any net component of transverse magnetization (M<sub>y</sub>) , perpendicular to the applied field H<sub>x</sub>. Extrapolated first-order reversal curve (FORC) diagrams were measured, out-of-plane and inplane. While the major hysteresis loops of all arrays have similar shapes, their FORC diagrams reveal distinct patterns, suggesting different magnetic behavior. The magnetic anisotropy can be controlled by the ratio of Cu to Ni thickness, the nanowire axis becoming harder as the ratio increases. In the out-of-plane direction, the maximum interaction field is proportional to the Ni thickness. The FORCs show evidence of a large coercive field distribution, which we attribute to the smaller interaction fields in the nanodiscs along the edges of the samples. In the inplane direction, depending upon the easy axis direction, there can be a mixture of nanodiscs reversed by coherent and incoherent rotation, or by incoherent rotation only.

  • Blocking and locking during rotational magnetization reversal in ferromagnetic thin films

    A model describing quasi-static partial rotation and dynamic noncoherent rotation is presented and shown to agree with experiment. It is shown that, with applied field rise times longer than 1 ns, the ripple can be expected to relax in equilibrium with the rotating means magnetization. Magnetostatic stray fields prevent blocking from strongly affecting the rotational process and permit a stable ripple configuration even beyond the critical astroid. At a defined applied field threshold the inhomogeneous portion of the effective field from uniaxial anisotropy and applied field overcomes the stabilizing effects of the magnetostatic stray fields in alternate half-wavelengths of the ripple causing the magnetization there to switch through a large angle. The predicted large angle switching of the magnetization in alternate half wavelengths of the ripple is in good agreement with experimentally observed bands or stripes of reversed and unreversed magnetization both during quasi- static reversals in inverted Permalloy films and during dynamic non-coherent rotation with applied field rise times longer than 1 ns in normal Permalloy films. The model presents a reasonable fit to the field dependence of the angle between the observed stripes and the uniaxial anisotropy axis. Magnitudes of the local anisotropy causing the ripple are obtained from the fit to the data and shown to agree with the values determined by transverse susceptibility measurements.

    Temporally and spatially resolved study of magnetization reversal in a 20/spl times/4 /spl mu/m, 50 nm thick permalloy sample was done using scanning Kerr microscopy. It is shown that the process starts with periodic-like instability, but then develops from both short edges towards the center. After switching the pulse field off, the initial condition is restored by creation of a domain along the long axis of the sample and gradual broadening of this domain.

  • Effect of interface on coupling of NiFeCo/TaN/NiFeCo sandwich films

    Coupled NiFeCo/TaN/NiFeCo films with coercivity of 0.42 and 5.94 Oe were obtained by varying the substrate bias conditions of the NiFeCo films. The film with low coercivity had a sharp magnetization reversal process, i.e. small switching field distribution. On the other hand, a large switching field distribution, approximately 3.5 Oe, was found on the sample film with high coercivity. Such different magnetic characteristic may be attributed to altering the domain wall energy associated with induced coupling at NiFeCo/TaN interface due to pit formation in the NiFeCo film.
