摘要：

Detailed theoretical and experimental investigations of the electronic and magnetic properties of the HoCo5-xSix Six compound (x = 0.5 and 1.0) have been performed. All theoretical investigations of the electronic and magnetic properties of the system have been done using the Korringa-Kohn-Rostoker (KKR) band structure method. The calculated magnetic moments range between 1.36 to 1.5 mu(B) per Co atom, depending on the crystal site. The calculations show a spin and orbital moment of Ho of 3.85 mu(B) and 5.46 mu(B), respectively, oriented antiparallel to the Co moments. These results are in reasonable agreement with macroscopic saturation magnetisation.
