Abstract

Fe₈₈Zr_8-xPr_xB₄ (x = 2, 4, 6) ribbons with a thickness of ∼40 μm were fabricated, but only the Fe₈₈Zr_8-xPr_xB₄ (x = 2, 4) samples can be quenched into fully amorphous state. The Fe₈₈Zr_8-xPr_xB₄ (x = 2, 4) amorphous ribbons exhibit higher Curie temperature (T_c) and maximum magnetic entropy change (−ΔS_m^peak) than those of the Fe₈₈Zr₈B₄ amorphous alloy, without significant coercivity and spin-glass-like behaviors. The almost highest value of −ΔS_m^peak near 320 K of the Fe₈₈Zr₄Pr₄B₄ amorphous alloy (∼4.0 J/(kg × K) under 5 T) makes it possible to construct several amorphous hybrids that exhibit specific table-shaped magnetic entropy change profiles with higher average −ΔS_m and effective refrigeration capacity within the working temperature intervals of various domestic magnetic refrigerating appliances.
