Abstract
We have investigated the effect of hydrostatic pressure (P) on ferromagnetic FM phase transition and magnetocaloric properties of (Sm0.8Nd0.2)0.52Sr0.48MnO3 single crystal. At ambient pressure, the system undergoes a first order FM transition associated with large magnetic entropy change ΔSM. The temperature distribution of ΔSM exhibits an asymmetric behavior with respect to TC. The application of pressure increases magnetization, shifts the FM transition to higher temperature, and weakens the metamagnetism. As a result, ΔSM decreases and its thermal distribution becomes more symmetric as compared to P=0.
