Temperature dependence of the magnetization curves under the ZFC process for (a) magnetic field applied along the a axis and (b) magnetic field applied along the c axis of the ErFeO3 single crystal.
Isothermal magnetization curves were measured from 3 K to 40 K under decreasing magnetic field for the ErFeO3 single crystal along the a, b, and c axes.
Temperature dependence of the magnetic entropy change of the ErFeO3 single crystal for (a) the a axis, (b) the b axis, and (c) the c axis.
RC versus magnetic field curves for b axis (black triangle line) and c axis (red square line) of the ErFeO3 single crystal.
The difference in ΔSM between the c and b axes of the ErFeO3 single crystal under different temperature and magnetic field.
Angle dependent magnetization curves measured by rotating the ErFeO3 single crystal from the c to b axis under different magnetic fields at 6 K.
(a) Isothermal magnetization curve for the b axis of the ErFeO3 single crystal at 6 K with experimental result (black squares) and fitted curve (red line). (b) The results of rotating field entropy change from c to b axis in a field of 3.6 T at 6 K were calculated from thermodynamic Maxwell relations (blue diamond) and Fermi-Dirac angle distribution (red circle), respectively.
