Abstract
Crystal structure and magnetic properties of Cerium-doped La1−yCeyFe11.44Si1.56 (y = 0.0 − 0.3) compounds are reported. The compounds possess the NaZn13-type cubic structure with ferromagnetic arrangement. The substitution of Ce into the host lattice slightly decreased the lattice constant from 1.1477 to 1.1471 Å, and as the doping content increased, the saturation magnetization and Curie temperature of the samples were also reduced. A large value of the magnetic entropy change ΔSm was observed at low doping concentration.
