Giant magnetocaloric effect in Tb3Rh

Tb3Rh exhibits a giant magnetocaloric effect (GMCE) around ordering temperature of 88 K. The maximum magnetic entropy change ΔSm obtained at 2 T, 3 T, 5 T and 7 T amounts −11.6 J/(K kg), −14 J/(K kg), −17.9 J/(K kg) and −21 J/(K kg) respectively. The origin of an enhanced MCE is related to a first-order magnetic transition. Magnetic frustration and short range correlation are very important in understanding the properties of Tb3Rh.
