Theoretical study of temperature dependence of spin susceptibility in anisotropic itinerant ferromagnets

Research output: Contribution to journalArticlepeer-review

Abstract

We developed a framework for directly calculating the spin susceptibility of anisotropic itinerant ferromagnets in the full temperature range within the coherent potential approximation in the disordered local moment picture. As a test of our formulation, we demonstrate the computation for the temperature (T) dependence of the spin susceptibility for Rashba-type ferromagnets with the Curie temperature TC. In a certain parameter, we found that the inverse transverse susceptibility 1=χ' const. for T < TC and 1=χ ∝ T − TC for T > TC, which reflects characteristics of itinerant ferromagnets including a spin-orbit interaction.
