摘要：
Two series of samples of the composition CuIn1-XCoXSe2 (m-series) and Cu1-X/2In1-X/2CoXSe2 (d-series) were prepared by solid-state synthesis and their magnetic properties were investigated. It was shown that cobalt is much better incorporated into the chalcopyrite matrix of the d-series samples, thus providing the onset of paramagnetic properties. Quenching allows the concentration of the incorporated cobalt to increase, which leads to the onset of weak ferromagnetism.
