Low Working Temperature of Erbium Orthophosphate ErPO4 with Large Magnetocaloric Effect
Erbium orthophosphate ErPO4 was successfully prepared. The XRD pattern analyses have proved that the ErPO4 crystallizes in the tetragonal structure (I41/amd). Under a magnetic field of 50 kOe, the magnetic entropy change (− ΔSM) reaches 23.78 J/kg K at 2.6 K for ErPO4. The value of the relative cooling power is 475 J/kg. The lowest temperature and the large MCE have inferred that ErPO4 is a potential candidate for sub-kelvin magnetic refrigeration applications.
