Abstract
Two series of cobalt-doped CuGa1 – xCoxSe2 and Cu1 – x/2Ga1 – x/2CoxSe2 chalcopyrites were prepared. Cobalt in part entered the chalcopyrite structure to ensure the appearance of paramagnetic properties, while in part it remained involved in cobalt selenide admixtures. High-temperature quenching forced almost all of the cobalt to enter the crystal structure in the Cu1 – x/2Ga1 – x/2CoxSe2 samples. Significant ferromagnetism appears in the Cu0.9Ga0.9Co0.2Se2 sample, which had the highest cobalt concentration, in particular at room temperature.
