Abstract
The magnetic properties and giant magnetic entropy change in gadolinium orthoferrite have been investigated for their potential application as magnetic refrigeration working media. We found GdFeO3 polycrystalline sample exhibits a large magnetic entropy change value (–ΔSM = 50.2 J/kg K at 70 kOe) near the liquid hydrogen temperature, which is much larger than those of other oxide magnetic refrigerators. The large magnetocaloric effect is related to the half-filled 4f electronic state in rare earth-transition oxides. The large values of these parameters, together with negligible hysteresis, suggest that GdFeO3 multiferroic ferrite could be potential materials for magnetic refrigeration in low-temperature region.
