【 摘 要 】

We have investigated the magnetocaloric effect across a first order structural transition coupled to the ferromagnetic transition (𝑇C ∼ 270 K) in Pr0.1Ce0.4Sr0.5MnO3 using magnetization and heat capacity measurements. The adiabatic magnetic entropy change |𝛥𝑆| obtained from magnetization measurements for a magnetic field change of 2 T is around 1.3 J/kg K. A similar value of |𝛥𝑆| was obtained from the analysis of heat capacity data.
