- 論文の詳細を見る
The electronic structure of Ni base ferromagnetic alloys with Co, Fe, Mn and Cr is discussed on the basis of the coherent potential approximation combined with the Hartee-Fock approximation for the electron-electron interaction. Calculations are carried out by use of a tight-binding single band model. With consistent choices of parameters the concentration dependences of the average magnetic moment of each constituent atom, the saturation magnetization, and the density of states at the Fermi level are calculated. The significance and limit of the coherent potential approximation for calculating the electronic structure of the ferromagnetic alloys are discussed in some detail.
