Magnetocaloric effect in Mn-containing Hitperm-type alloys.

The magnetocaloric effect of Fe60−xMnxCo18Nb6B16 x=0,2,4 is studied. Mn addition decreases the Curie temperature of the alloys but also reduces the peak entropy change and the refrigerant capacity of the material. The estimated adiabatic temperature change, for a maximum applied field of 15 kOe, is...
