Anisotropic and incommensurate spin fluctuations in hcp iron and some other nearly magnetic metals

V. Thakor, J. B. Staunton, J. Poulter +3

We present an ab initio theoretical formalism for the static paramagnetic spin susceptibility of metals at finite temperatures. Since relativistic effects, e.g. spin-orbit coupling…

Fermi surface origin of the interrelationship between magnetocrystalline anisotropy and compositional order in transitional metal alloys

S. S. A. Razee, J. B. Staunton, B. Ginatempo +2

Recently, we outlined a scheme to investigate the effects of compositional order on the magnetocrystalline anisotropy of alloys from a first-principles electronic structure point o…

Ab-initio Theoretical Description of the Interrelation between Magnetocrystalline Anisotropy and Atomic Short-Range Order

S. S. A. Razee, J. B. Staunton, B. Ginatempo +2

The cubic lattice symmetry of ferromagnetic homogeneously disordered alloys is when a compositional modulation is imposed. This can have a profound influence on the magnetocrystall…

Incommensurate and Commensurate Antiferromagnetic Spin Fluctuations in Cr and Cr Alloys from Ab Initio Dynamical Spin Susceptibility Calculations

J. B. Staunton, J. Poulter, B. Ginatempo +2

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 Fu…
