The Study of the Electronic Structure of CrPt$\text{}_{3}$ Alloy by the LMTO Method

The ab initio self-consistent linear muffin-tin orbital calculations in the atomic sphere approximation have been performed for the ordered CrPt$\text{}_{3}$ (AuCu$\text{}_{3}$-type structure) alloy. The band structure and the densities of electronic states are presented. The para- and ferrimagnetic phases were considered. The spin-polarized calculations have confirmed the experimental observation of small antiparallel induced magnetic moment on a platinum atom.
