Crystallographic structure, magnetic properties, and magnetic entropy change of the Cr-based spinel sulfides.Co1−xCuxCr2S4 (x = 0–0.8) have been investigated. All these compounds crystallize into the cubic spinel structure, the Cu.substitution shrinks linearly the lattice constant at a ratio of 0.0223 A per Cu atom in the unit cell, and enhances linearly ˚.the Curie temperature and the spontaneous magnetization at the rates of 18 K and 0.33 µB/f.u. per Cu atom in the unit cell,.respectively. All these compounds show a typical behavior of second order magnetic transition, and a room temperature.magnetic entropy change of 2.57 J/kg·K is achieved for Co0.4Cu0.6Cr2S4.
