Description
The effect of hydrostatic pressure on Curie temperature, the critical exponents and entropy change in La0.7Ca0.3MnO3 are determined. The pressure increases the Curie temperature. The combined magnetic entropy change, due to both magnetic field and pressure application, is found to be significant. It suggests that manganites are suitable candidates as barocaloric refrigerants near room-temperature region.
