摘要：
In this paper, a numerical model of an Active Magnetic Regenerator (AMR) for refrigeration at room temperature has been evaluated. The model is based on the equation of state of a homogeneous ferromagnetic with reference to the gadolinium used as magnetocaloric substance. In this way the curves of the magnetisation and of the specific heat at constant magnetic field and of the adiabatic temperature variation for the gadolinium subject to a variable magnetic field have been obtained using the Brillouin function.
