Theoretical Study of Temperature Dependence of Spin Susceptibility in Anisotropic Itinerant Ferromagnets

We developed a framework for directly calculating the spin susceptibility of anisotropic itinerant ferromagnets in full temperature range within coherent potential approximation disordered local moment picture. As test our formulation, we demonstrate computation ($T$) dependence Rashba-type with Curie $T_\mathrm{C}$. In certain parameter, found that inverse transverse $1/\chi_\perp\simeq\mathrm{const.}$ $TT_\mathrm{C}$, which reflects characteristics including spin-orbit interaction.
