We present results for the specific heat of a Nd1/2Sr1/2MnO3 crystal. The continuous phase transition from paramagnet to metallic ferromagnet is observed at 250K and a first order transition from metallic ferromagnet to the insulating charge ordered state is observed at 150K in zero field. Hysteresis is observed on warming and cooling, which increases in a magnetic field. The magnetic field is seen to drive the low temperature charged ordered state into the ferromagnetic state through a first order transition.
