Abstract
The magnetocaloric effect (MCE) in the UNiGa compound has been studied using the dc magnetization measurement technique. This system shows normal and inverse MCEs at low field around the paramagnetic to ferrimagnetic transition temperature (38.4 K), and the ferrimagnetic to antiferromagnetic transition temperature (34.5 K), respectively. At higher fields, the inverse MCE becomes very weak, which could be explained due to the presence of a field-induced metamagnetic phase transition. The maximum value of the magnetic entropy change -ΔSM, for Δμ0H = 5T, has been found to be 3.56 J kg-1 K-1 at ∼37.2K with a relative cooling power of 22.5 J kg-1.
