The ab initio self-consistent linear muffin-tin orbital calculations in the atomic sphere approximation have been performed for the ordered CrPt_{3} (AuCu_{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.
