Abstract
The structure and magnetic properties of Nd5Si3 compound have been investigated. A reversible magnetic entropy change was observed at about 112 K accompanied with a second-order magnetic transition from the ferromagnetic to paramagnetic state. The maximum value of −ΔSM is 5.0 J kg−1 K−1 at 112 K for a magnetic field change of 50 kOe. The relatively large magnetic entropy change and broad working-temperature span (about 57 K) of the reversible magnetocaloric effect make the present compound a potential candidate for the practical magnetic refrigeration in this temperature range.
