An experimental and theoretical study of magnetocaloric effect in NdDyFeO.

A significant magnetocaloric effect (MCE) has been revealed in our investigation on polycrystalline NdDyFeO below 30 K. Observed magnetization of the system at low temperature is 32% higher than the expected average magnetization of NdFeO and DyFeO. Such an enhancement in the magnetization led to a large change in magnetic entropy (10.
