Patra, S. Majumdar, S. Giri, G. Iles, T. Chatterji] We report the magnetocaloric effect (MCE) in a Pr0.52Sr0.48MnO3 single crystal estimated from the isothermal magnetization curve using the Maxwell relation. Isothermal magnetization curves are measured over the range 20K to 320K where the field was applied parallel (‖) and perpendicular (⊥) to the [110] direction of the perovskite structure with Pbnm space group. Apeak in the temperature (T) dependence of magnetic entropy change (ΔS M) with a fairly large negative value (≈−3.3J/kg K) is observed at 275K close to the Curie temperature (T C) for a change in field of ΔH=40kOe. The ‖ and ⊥ components of ΔS M deviate from each other below ∼260K and an inverse MCE is observed below ∼150K. We note that the Landau theory of phase transitions satisfactorily explains the ΔS M vs T plot around the second-order transition at T C.
