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

Two series of manganese-doped chalcopyrite CuGaSe2 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 degrees C has made it possible to considerably increase the ferromagnetic response, which begins to rise starting at a certain doping level.

Automated 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.
