Using a first-principles, relativistic electronic structure theory of finite temperature metallic magnetism, we investigate the variation of magnetic anisotropy K with magnetization M in metallic ferromagnets. We apply the theory to the high uniaxial K material, L1(0)-ordered FePt, and find its magnetic easy axis perpendicular to the Fe/Pt layers for all M(More)
A scheme for making ab-initio calculations of the dynamic paramagnetic spin susceptibilities of solids at finite temperatures is described. It is based on Time-Dependent Density Functional Theory and employs an electronic multiple scattering formalism. Incommensurate and commensurate anti-ferromagnetic spin fluctuations in paramagnetic Cr and(More)
The concentration-dependent position of the diffuse peaks in electron and x-ray diffraction patterns of Cu1-xPdx alloys in the disordered state is attributed to Fermi surface nesting. We present the first experimentally determined Fermi surfaces of Cu0.72Pd0.28 and Cu0.6Pd0.4, and show that they do indeed possess significant flat areas capable of nesting.(More)
