Thermal properties, magneto- and baro-caloric effects in La0.7Pb0.3MnO3 single crystal

The results of heat capacity, thermal dilatation and T-p phase diagram studies on the La0.7Pb0.3MnO3 single crystal are reported. Direct measurements of intensive magnetocaloric effect are performed by means of adiabatic calorimeter. Barocaloric effect is determined using data of heat capacity and susceptibility to hydrostatic pressure. Caloric efficiency of manganite in the vicinity of ferromagnetic phase transition is discussed and compared with that of other magnetic materials. (C) 2013 American Institute of Physics.
