Zusammenfassung:— Two series of manganese-doped chalcopyrite CuGaSe 2 samples have been prepared by solid-state reactions. Because of its low solubility, the manganese is distributed between chalcopyrite lattice sites, ensuring paramagnetic properties, and manganese-containing antiferromagnetic impurity phases. Quenching the samples from 1000°C has made it possible to considerably increase the ferromagnetic response, which begins to rise starting at a certain doping level.
