摘要
In this paper, we calculate the adiabatic temperature change and the isothermal magnetic entropy change upon magnetic field variations in the Laves phase pseudobinary (Er1-cDyc)Co-2. We also propose three composite materials, formed by combining samples of the pseudobinary (Er1-cDyc)Co-2, with different Dy concentration, to work as refrigerant in temperature ranges from 33 to 60 K; from 70 to 105 K and from I 10 to 140 K respectively.
