Perpendicular Magnetic Anisotropy and Strain in Evaporated Co-Pt and Co-Pd Alloys

Abstract

An x-ray diffraction study has been carried out to study vertical lattice strain in polycrystalline HV evaporated Co-Pt and Co-Pd alloys and UHV evaporated Co-Pt alloys on SiN buffered fused silica substrates. The data support an inhomogeneity model, which was proposed to explain the occurence of perpendicular magnetic anisotropy in these alloys. The effect of subatomic layering on magneto-optic properties in 100nm thick HV evaporated C0 2S Pt 72 is reported.

Irreversible modification of magnetic properties of Pt/Co/Pt ultrathin films by femtosecond laser pulses

“…24 In fact, a correlation between these two quantities is found in our results. The magnetic properties of the Co-Pt alloys strongly depend on concentration, 25 crystallographic structure, 26 as well as a degree of order.…”

Inelastic neutron scattering and migration energies in FePd

“…After a period of strong research on superalloys for their magnetic [1][2][3][4][5], catalytic [6] and high temperature mechanical [7] properties, nowadays some of them arouse a new interest owing to their possible applications as shape memory alloys [8] and high density recording media because of their large magnetic anisotropy [9,10]. A good knowledge of the ordering processes and of its dynamics is thus a necessary step in any extensive research on those systems.…”

XMCD at the L 2,3-edges of Pt in ordered TPt3 alloys (T = Cr, Mn, Co)

“…Among the alloys of the 3d ferromagnetic transition metal elements and the 5d non-magnetic elements, the ordered TPt3 alloys (T = V, Cr, Mn, Fe and Co) crystallizing in the Cu3Au structure have attracted much attention because of their interesting magnetic properties (i.e., a large Kerr rotation at short wavelength or/and a strong magneto-crystalline anisotropy (Suzuki et al, 1997;Weller et al, 1993)). Also, these compounds are model systems for the study of the magnetic properties of 3d-5d systems since one would expect to find systematic and linear trends with the filling of the 3d band.…”
