Abstract
Structural and magnetic properties of an intermetallic Ho2Rh3Ge compound have been investigated in this paper. We report the observation of large magnetocaloric effect (MCE) in Ho2Rh3Ge from the characterization of magnetism isotherms. The Rietveld refinement of powder X-ray diffraction revealed that Ho2Rh3Ge crystallizes in a rhombohedral Laves phase structure (space group R3̄m, hR18). It exhibits ferromagnetic order below the Curie temperature TC = 13 K. Around TC, maximum value of entropy change −ΔSm = 25.4 J kg−1 K−1 was observed for a change of magnetic field 0−8 T. The obtained refrigeration capacity (relative cooling power) for a change of magnetic field from 0 8 T is 497(664) J.kg−1. The second–order magnetic phase transition in Ho2Rh3Ge is confirmed from Arrott plots, universal scaling plots of magnetic entropy changes, and also from the field dependence of the magnetic entropy change.
