Abstract
The magnetocaloric effect is calculated for La1-x Ce x MnO3 system near a phase transition from ferromagnetic to paramagnetic state as a function of temperature. It is suggested by the results that La1-x Ce x MnO3 material can be utilized as the working material in an active magnetic regenerative refrigerator with large temperature span, for its significant entropy change upon the application of a magnetic field and the easily tuned Curie temperature.
