Abstract: An overview of the magnetocaloric properties of the MnAs1-xSbxis presented. The temperature dependence of the isothermal magnetic entropy, ΔSmag, and the refrigerant capacity, RC, have been investigated theoretically and experimentally in a composite based on second order MnAs1-xSbxphases. This work demonstrates the outstanding agreement between the experimental results and the continuous curves predicted by numerical calculations, indicating that this approach can be used to design magnetic refrigerant materials with enhanced magnetocaloric response in magnetic refrigerator performing an Ericsson cycle near room temperature.
