Magnetic properties and large isothermal entropy change in Mn(2-x)Fe(x)P(0.6)Si(0.25)Ge(0.15) compounds.
Author(s) : WANG G. F., PALACIOS E., BURRIEL R., et al.
Summary
The authors have reported the structural, magnetic and magnetocaloric properties of these compounds with x= 0.7, 0.8, 0.9, and 1.0. XRD powder patterns confirm that the samples crystallize mainly in Fe2P-type hexagonal structure, and contain a small amount of MnFe(2)Si(delta)Ge(1-delta) as an impurity. Both, the Curie temperature and saturation magnetization decrease with increasing Mn concentration. The maximum values of isothermal entropy change are 8.9, 14.9, 22.2 and 22.4 J/kg.K for x= 0.7, 0.8, 0.9, and 1.0 under a field change of 9 T, respectively. The large MCE and the broad range of working temperatures indicate that these materials are promising candidates as working refrigerants for room-temperature magnetic refrigeration.
