Abstract: The optical and magneto-optical properties of bulk [L2.sub.1] ordered [Co.sub.2]CrGa Heusler alloy (HA) are examined below and above the Curie temperature and are explained in terms of the band structure. The studies have shown that unlike bulk [L2.sub.1]-type ordered [Co.sub.2]CrGa HA sample, B2 structure order of [Co.sub.2]CrGa HA films have displayed negative temperature coefficient of resistivity.
