摘要

The magnetocaloric effect (MCE) of Nd0.5Sr0.5MnO3 (NSM) samples made at various calcination temperatures (Tcalcin) is simulated using a phenomenological model (PM). The results indicated that MCE in NSM samples is strongly dependent on Tcalcin, achieving conventional MCE for NSM samples. The thermomagnetic characteristic of bulk NSM sample NSM covers both conventional and inverse MCE. The MCE in NSM improves dramatically as Tcalcin increases. The calcination is asserted to be an effective tool for increasing MCE for NSM. Some MCE parameters of NSM are comparable or higher than ones of published works. The MCE in an NSM system has a wide temperature range, which is appealing to MR.
