Cobalt-doped chalcopyrites CuInSe2: the synthesis and magnetic properties

M. A. Zykin et al.

Summary: The magnetic properties of two series of CuIn1-XCoXSe2 and Cu1-X/2In1-X/2CoXSe2 samples were investigated. It was found that cobalt was better incorporated into the matrix of one series, resulting in the onset of magnetic properties.

Synthesis and Magnetic Properties of CuGaSe2:Mn Manganese-Doped Chalcopyrites

M. A. Zykin et al.

Summary: Two series of manganese-doped chalcopyrites, Cu1-x/2Ga1-x/2MnxSe2 and CuGa1-xMnxSe2, were synthesized by solid-phase synthesis. Manganese-containing impurities were found in all samples due to the low solubility of manganese in chalcopyrite CuGaSe2. However, manganese was incorporated into the chalcopyrite structure in a significant amount. All manganese-containing chalcopyrites exhibited mainly paramagnetic properties, but a ferromagnetic contribution was found in all samples.

Increased Manganese Solubility and Ferromagnetic Signal in Chalcopyrite CuGaSe2:Mn as a Result of High-Temperature Quenching

M. A. Zykin et al.

Summary: Two sets of manganese-doped chalcopyrite CuGaSe2 samples were prepared through solid-state reactions. Due to its low solubility, manganese is distributed between the chalcopyrite lattice sites, exhibiting paramagnetic properties and containing manganese-containing antiferromagnetic impurity phases. Quenching the samples from 1000 degrees C significantly enhances the ferromagnetic response, which starts to increase at a certain doping level.
