Magnetic properties and magnetocaloric effect of MnFeP0.5Ge0.5-xSix compounds

We have studied the magnetic properties and magnetic-entropy changes of the MnFeP0.5Ge0.5-xSix compounds with x = 0.,0.,0.,0.4 and 0.45. X-ray diffraction shows that the compounds crystallize in the Fe2P-type hexagonal structure. The lattice parameter a and the Curie temperature decreases with incre...

Zusammenfassung:	We have studied the magnetic properties and magnetic-entropy changes of the MnFeP0.5Ge0.5-xSix compounds with x = 0.,0.,0.,0.4 and 0.45. X-ray diffraction shows that the compounds crystallize in the Fe2P-type hexagonal structure. The lattice parameter a and the Curie temperature decreases with increasing x. The maximal magnetic-entropy changes for x = 0.4 and 0.45 derived from the magnetization data are about 6.0 J/kg K and 5.8 J/kg K, respectively, for a field change from 0 to 1.5 T.
