“…The crystal structure of Cu 2+ containing spinels is sensitive to the thermal history of the samples. Further, it has been reported that CuFe 2 O 4 is an unique spinel because its cation distribution is strongly temperature dependant and the presence of Cu 2+ ions leads to severe Jahn-Teller type distortion of sites [1]. The selective dilution of tetrahedral (A) and octahedral (B) sites may lead to non-collinear spin structure.…”
