Magnetocrystalline anisotropy in permalloy revisited.

Permalloy with a body-centered-cubic structure has been grown on GaAs(001) by molecular beam epitaxy. Its magnetism, Curie temperature, and magnetic anisotropy are determined experimentally and compared to those of conventional face-centered-cubic Permalloy. Unexpectedly the vanishing magnetic cubic anisotropy in Permalloy is found to be independent of its atomic structure but depends only upon...

Strongly Localized Magnetization Modes in Permalloy Antidot Lattices

Low frequency noise and complex AC magnetoresistance in superconducting Pb/Ge with square antidot lattice

The low frequency voltage noise and complex AC voltage response to weakly modulated magnetic fields have been studied in a superconducting Pb film with a square lattice of antidots. The temperature was close to Tc and the DC magnetic field was changed between ±1.5 H1 with H1 1⁄4 9:2 Oe corresponding to one vortex per antidot. A narrow band noise near f 0:55 Hz has been observed which shows diff...

Magnetic Properties in a Spin-1 Random Transverse Ising Model on Square Lattice

In this paper we investigate the effect of a random transverse field, distributed according to a trimodal distribution, on the phase diagram and magnetic properties of a two-dimensional lattice (square with z=4),  ferromagnetic Ising system consisting of magnetic atoms with spin-1. This study is done using the effectivefield theory (EFT) with correlations method. The equations are derived using...
