Incommensurate and commensurate antiferromagnetic spin fluctuations in cr and cr alloys from ab initio dynamical spin susceptibility calculations

Incommensurate and commensurate antiferromagnetic spin fluctuations in cr and cr alloys from ab initio dynamical spin susceptibility calculations

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 antiferromagnet...
