Temperature dependence of magnetic moment of rare earth ions in ErFeO₃ and NdFeO₃ single crystals

Abstract

Interaction between rare earth and iron spins in rare earth orthoferrites leads to remarkable phenomena, such as spontaneous magnetization reversal and spin-flip process. This is despite the rare earth spins...

Metamagnetic phase transition induced large magnetocaloric effect in a Dy0.5Ho0.5MnO3 single crystal

“…8,9 Typical materials include rare-earth-based compounds RMO 3 (M = Fe, Mn, Cr, etc.) [10][11][12][13][14][15] and R 2 N 2 O 7 (N = Ni, Co, Al). [16][17][18][19][20] Magnetic refrigeration can be achieved in two ways: one involves exploiting the magnetocaloric effect (MCE) by manipulating the magnetic field, which is accompanied by a large change in magnetic entropy (DS m ) and eventually leads to a large adiabatic temperature change (DT ad ); another technique relies on the rotation of the crystal or magnetic field based on the ''rotating MCE'' (RMCE), 15,21,22 which necessitates high anisotropic energy in the crystal.…”
