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