Abstract
The magnetocaloric effect of Fe 80− x B 12Cr 8Gd x ( x = 1, 2, 3, 5, 8, 10, 11) amorphous alloys was studied. Gd addition increases the thermal stability of the alloy and allows tuning the Curie temperature ( T C). A linear relationship between the magnetic entropy change and the magnetic moment of the alloy was observed. The experimental values of magnetic field dependence of the magnetic entropy change were consistent with a phenomenological universal curve. The maximum magnetic entropy change, for x = 1, was ∼33% larger than Fe 80B 12Cr 8, the refrigerant capacity ( RC) is ∼29% larger than Gd 5Si 2Ge 1.9Fe 0.1 and within 10% of Fe 82.5Zr 7B 4Co 2.75Ni 2.75Cu 1 which is the best Fe-based amorphous MCM to date. The tunable T C can be used to increase RC and the temperature span of layered multi-composition magnetocaloric regenerators.
