Influence of nano-VC on the structural and magnetic properties of MnAlC-alloy.

Alloys of MnAlC with additions of VC nano-particles have been synthesized and their properties evaluated. The MnAlC(VC) (x = 0.25, 0.

Resonant x-ray diffraction revealing chemical disorder in sputtered L10 FeNi on Si(0 0 1).

In the search for new rare earth free permanent magnetic materials, FeNi with a L10 structure is a possible candidate. We have synthesized the phase in the thin film form by sputtering onto HF-etched Si(0 0 1) substrates. Monatomic layers of Fe and Ni were alternately deposited on a Cu buffer layer, all of which grew epitaxially on the Si substrates.

Tailoring magnetism at the nanometer scale in SmCo5 amorphous films.

The thickness dependence of magnetic properties has been studied in SmCo5 amorphous films with imprinted in-plane anisotropy for thicknesses ranging down to the nanometer scale (2.5-100 nm). The field induced in-plane magnetic anisotropy decreases considerably when the film thickness is below 20 nm.

Perpendicular magnetocrystalline anisotropy in tetragonally distorted Fe-Co alloys.

We report on the experimental realization of tetragonal Fe-Co alloys as a constituent of Fe0.36Co0.64/Pt superlattices with huge perpendicular magnetocrystalline anisotropy energy, reaching 210 microeV/atom, and a saturation magnetization of 2.
