Temperature dependent magnetic anisotropy in metallic magnets from an ab-initio electronic structure theory: L1_0-ordered FePt
J. B. Staunton, S. Ostanin, S. S. A. Razee +4
On the basis of a first-principles, relativistic electronic structure theory of finite temperature metallic magnetism, we investigate the variation of magnetic anisotropy, K, with…
An ab-initio theoretical investigation of the soft-magnetic properties of permalloys
S. Ostanin, J. B. Staunton, S. S. A. Razee +2
We study Ni80Fe20-based permalloys with the relativistic spin-polarized Korringa-Kohn-Rostoker electronic structure method. Treating the compositional disorder with the coherent po…
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…
