“…%) [ 7 ], in Fe 80-x M x B 10 Zr 9 Cu 1 (M = Ni, Ti; x = 0, 3, 5) [ 8 ] and in Fe 86−x B x Mn 4 Zr 8 Nb 2 (x = 4, 8, 12, 16 and 20 at. %) [ 9 ] multicomponent amorphous alloys. The modest peak values of ∆ S M are usually accompanied by a broad full width at a half maximum in the materials, showing the second-order ferromagnetic–paramagnetic phase transition, resulting in a large refrigerant capacity (RC).…”

The microstructure, revealed by X-ray diffraction and transmission Mössbauer spectroscopy, magnetization versus temperature, external magnetizing field induction and mechanical hardness of the as-quenched Fe75Zr4Ti3Cu1B17 amorphous alloy with two refractory metals (Zr, Ti) have been measured. The X-ray diffraction is consistent with the Mössbauer spectra and is characteristic of a single-phase amorphous ferromagnet. The Curie point of the alloy is about 455 K, and the peak value of the isothermal magnetic entropy change, derived from the magnetization versus external magnetizing field induction curves, equals 1.7 J·kg−1·K−1. The refrigerant capacity of this alloy exhibits the linear dependence on the maximum magnetizing induction (Bm) and reaches a value of 110 J·kg−1 at Bm = 2 T. The average value of the instrumental hardness (HVIT) is about 14.5 GPa and is superior to other crystalline Fe-based metallic materials measured under the same conditions. HVIT does not change drastically, and the only statistically acceptable changes are visibly proving the single-phase character of the material.

“…It has been found that amorphous Fe 82 Mn 8 Zr 10 alloy exhibited large MCE (−∆S T = 2.87 J/kgK for a field change of 5 T) at T C = 210 K just below room temperature [12]. The T C of Fe-Zr-based amorphous alloys could be improved by doping B and/or Co to cover the room-temperature region [10,13,14,15,16,17,18] [15]. The present work presents the influence of Co-doping on the magnetic properties, MCE and RC of Fe-Co-Mn-Zr-Nb-B amorphous ribbons.…”
