Barahona Huenchumil, Patricia Mabel; Galdámez Silva, Antonio; López Vergara, F.; Manríquez Castro, Víctor; Peña, O. (Elsevier, 2014)CuTi2−xM xS4 (M =Fe, Mn, Co; x =0.3, 0.5) and CuCr2−xTixSe4 (x =0.3, 0.5, 0.7) chalcospinels were synthesized by conventional solid-state reactions. Their crystal structures were determined by single-crystal X-ray ...
