Abstract

The magnetocaloric effect (MCE) is investigated for La0.7SrxMnO3−δ (0.1 ≤ x ≤ 0.3) system closes to a phase transition from a ferromagnetic to a paramagnetic state. The results recommend that La0.7SrxMnO3−δ (LSMO) samples have potential application as a magnetic refrigerant (MR) in an extended temperature range. Consequently, it is hoped that LSMO samples can be MR materials in low magnetic field shifts.
