Spin polarized energy band structure of SmCo5

The electronic energy band structure and magnetic moment of the intermetallic compound SmCo5have been determined by a self-consistent spin-polarized APW method. The calculated magnetic moment is in good agreement with the measured value. The calculated energy bands show a striking similarity to those of pure Co. These results form the foundation of a theory of the electronic structure of all the RCo5- type intermetallic compounds of the same crystal structure.
