英文摘要	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 angstrom 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 mu(B)/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.
