Abstract

Mn-Fe-P-Ge alloys are highly attractive magnetocaloric materials for near room temperature magnetic cooling applications. The structural and magnetic phase transition of a Mn_1.1Fe_0.9P_0.74Ge_0.26 alloy was investigated and an Arrott plot analysis conducted. It was found that this alloy exhibits ferromagnetism at room temperature and the magneto-structural transition responsible for the magnetocaloric effect was first order in nature.
