Resumen o descripción

"The temperature dependence of the isothermal magnetic entropy change, Delta S-M, and the magnetic field dependence of the refrigerant capacity, RC, have been investigated in a composite system xA + (1 - x) B, based on Fe87Zr6B6Cu1 (A) and Fe90Zr8B2 (B) amorphous ribbons. Under a magnetic field change of 2 T, the maximum improvement of the full-width at half maximum of Delta S-M(T) curve (47% and 29%) and the RC (18% and 23%), in comparison with those of the individual alloys (A and B), is observed for x approximate to 0.5. Moreover, a flattening over 80K in the Delta S-M(T) curve around room temperature range is observed, which is a key feature for an Ericsson magnetic refrigeration cycle."
