    • Abstract

       

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