The Magnetocaloric Properties of (Mn_1-XFe_X)₅Sn₃ Compounds Prepared in Magnetic Environment

Abstract:

The crystal structure, microstructure, Curie temperature and magnetocaloric properties of (Mn_1-xFe_x)₅Sn₃ (x=0.1~0.5) alloys were studied in this paper. The alloys were prepared by powder metallurgy method with magnetic pressing and magnetic sintering. All samples crystallize in the hexagonal InNi₂-type structure with space group P6₃/mmc. The lattice parameter, cell volumes of the (Mn_1-xFe_x)₅Sn₃ decrease with increasing x, while the Curie temperature of these alloys increases almost linearly with increasing x. All samples exhibit a moderate magnetocaloric effect, and the curves of magnetic entropy change are flat in a wide temperature range, which is suitable for the Ericsson cycle.
