摘要：
The magnetocaloric effect in NdMnO3 perovskite is investigated by using the Monte Carlo simulations. The Curie temperature T-C of NdMnO3 compound is deduced from the variation of the magnetization vs. the temperature with different values of external magnetic field. The variation of magnetization with the external magnetic field H is given. The specific heat with the temperature is established for different external magnetic field. The thermal magnetic entropy for different external magnetic field and different exchange interactions in NdMnO3 compound is obtained. The adiabatic temperature change is obtained. The relative cooling power with different external magnetic field is established. The magnetocaloric effect has been investigated from magnetization. (C) 2015 Elsevier B.V. All rights reserved.
