Abstract
Electronic structure of d electrons in pseudo-binary compounds Hf(Fe,Co)2 with the cubic Laves structure is calculated in the tight-binding approximation and the virtual crystal approximation. The concentration dependence of the magnetic moment is calculated in the mean-field approximation and good agreement between the calculated and observed results is obtained. It is shown that the metamagnetic transition (MT) occurs in the small concentration range just before the onset of the magnetic moment. The MT of other pseudo-binary compounds Sc(Fe,Co)2, Y(Fe,Co)2 and Lu(Fe,Co)2 is also discussed.Keywords
