Calculation of Electronic Structure of Fe Base bcc Ferromagnetic Alloys in the Coherent Potential Approximation

抄録

The electronic structure of bcc ferromagnetic Fe_1−xNi_x, Fe_1−xCo_x, Fe_1−xMn_x and Fe_1−xCr_x is discussed on the basis of the coherent potential approximation. The differences in the concentration dependences of the saturation magnetization and the electronic specific heat between Fe_1−xNi_x and Fe_1−xCo_x can be explained reasonably. The calculation yields a good agreement with experiment for Fe_1−xMn_x and Fe_1−xCr_x.
