“…Recent studies show that minor additions of Gd or Dy elements increase the value of ∆S M while the excessive addition of Gd or Dy causes the value of ∆S M to decrease [14]. However, Ce element addition leads to the decrease of ∆S M [15] in Fe-Si-Nb-B-Cu metallic glasses. The addition of transition metals usually increases the T C and ∆S M of Fe-based amorphous alloys due to the stronger atomic exchange interaction.…”

In this work, Fe80-xMxP13C7 (M = Co, Ni; x = 0, 5 and 10 at.%) bulk metallic glasses (BMGs) were prepared, and the effect of the Co/Ni elements substitution for Fe on the magnetocaloric properties of Fe80P13C7 BMG has been investigated systematically. The Curie temperature (TC) of the present Fe-based BMGs increases with the substitution of Fe by Co/Ni. The magnetic entropy change (ΔSM) of the present Fe-based BMGs increases first and then decreases with the increase of Fe substituted by Co, but monotonically decreases with the increase of Fe substituted by Ni. Among the present Fe-based BMGs, the Fe75Co5P13C7 BMG exhibits the maximum ΔSM value of 5.21 J kg−1 K−1 at an applied field of 5 T, which is the largest value among Fe-based amorphous alloys without any rare earth elements reported so far. The present Fe-based BMGs exhibit the large glass forming ability, tunable TC and enhanced ΔSM value, which are beneficial for magnetic refrigerant materials.

“…The typical material for the latter group is heat-treated Gd 0.54 Er 0.46 NiAl compounds with hexagonal ZrNiAl-type crystal structure, which exhibit a nearly temperature independent |∆S M | of 13 J•kg −1 •K −1 over the temperature region of 15-45 K for a field change of 0-5.32 T [6]. While, for the former group, there are two common strategies to combine multiple phases undergoing neighboring phase transitions, one is manufacturing the composites by artificially mixing, bonding, pressing or sintering [7][8][9][10], and the other is preparing the multi-phase materials by traditional producing techniques, like casting and heat-treatment [11][12][13][14][15].…”

To investigate the effect of crystallization treatment on the structure and magnetocaloric effect of Gd60Co40 amorphous alloy, the melt-spun ribbons were annealed at 513 K isothermally for 20, 40 and 60 min. The results indicate that, with increasing annealing time, the Gd4Co3 (space group P63/m) and Gd12Co7 (space group P21/c) phases precipitated from the amorphous precursor in sequence. In particular, in the samples annealed for 40 and 60 min, three successive magnetic transitions corresponding to the phases of Gd4Co3, Gd12Co7 and remaining amorphous matrix were detected, which induced an overlapped broadened profile of magnetic entropy change (|ΔSM|) versus temperature. Under magnetic field changing from 0 to 5 T, |ΔSM| values of 6.65 ± 0.1 kg−1·K−1 and 6.44 ± 0.1 J kg−1·K−1 in the temperature spans of 180–196 K and 177–196 K were obtained in ribbons annealed for 40 and 60 min, respectively. Compared with the fully amorphous alloy, the enhanced relative cooling power and flattened magnetocaloric effect of partially crystallized composites making them more suitable for the Ericsson thermodynamic cycle.
