Critical magnetic and magnetocaloric behavior of amorphous melt-extracted Gd50(Co69.25Fe4.25Si13B13.5)50 microwires
(2019-07)We report on the structural, magnetic, and magnetocaloric properties and critical behavior of high-quality amorphous melt-extracted Gd50(Co69.25Fe4.25Si13B13.5)50 alloy microwires with an average diameter of 42 μm. The ... -
Design and fabrication of a cryogenic magnetocaloric composite by spark plasma sintering based on the RAl2 Laves phases (R= Ho, Er)
(2020-08-05)We report the design and fabrication of a highly dense (>97%) two-phase magnetocaloric composite operating in the cryogenic temperature range based on the binary Laves phases HoAl2 and ErAl2 with a nearly table-like magnetic ... -
Enhanced refrigerant capacity and Curie temperature of amorphous Gd60Fe20Al20 microwires
(2019-10-30)Gd60Fe20Al20 microwires with an average diameter of ∼44 μm were fabricated by the melt-extraction method. XRD, TEM and HRTEM confirmed the amorphous nature of the microwires. The dimensional and chemical uniformity of the ... -
Large magnetic entropy change and refrigeration capacity around room temperature in quinary Ni41Co9-xFexMn40Sn10 alloys (x= 2.0 and 2.5)
(2020-06-05)We report the magnetocaloric properties of two Fe-containing quinary bulk polycrystalline alloys of nominal compositions Ni41Co7Fe2Mn40Sn10 and Ni41Co6.5Fe2.5Mn40Sn10 that were determined by indirect and direct methods. ... -
Large reversible magnetic entropy change in rapidly solidified Ni0.895Cr0.105MnGe1.05 melt-spun ribbons
(2018-06-01)The crystal structure, and magnetic and magnetocaloric properties of rapidly solidified Ni0.895Cr0.105MnGe1.05 melt-spun ribbons is reported. The ribbon samples crystallize into a single-phase hexagonal Ni2In-type structure ... -
Magnetoelastic transition and magnetocaloric effect in induction melted Fe100-xRhx bulk alloys with x = 50, 51
(2021-03-23)Magnetoelastic transitions (METs) in bulk in nearly equiatomic Fe-Rh alloys produced by arc melting may show poor reproducibility related to insufficient chemical homogeneity and presence of impurity phases in variable ... -
Ni-Co-Mn-Sn quaternary alloys: magnetic hysteresis loss reduction and ductility enhancement by iron alloying
(2019-09-01)The influence of Fe-alloying on the structural transition temperatures, microstructure, and mechanical and magnetocaloric properties of polycrystalline Ni41Co9−xFexMn40Sn10 (at. %) (x = 0–3) alloys has been studied. The ... -
Phase transformation and magnetocaloric effect of Co-doped Mn–Ni–In melt-spun ribbons
(2020-08-06)Ribbon-shaped magnetocaloric materials are favorable to achieve high heat-transfer efficiencies due to their large specific surface area. In this work, Mn50Ni41−xIn9Cox (0 ≤ x ≤ 4) ribbons were prepared using a melt-spinning ... -
The effect of cooling rate on magnetothermal properties of Fe49Rh51
(2020)We have investigated the effects of quenching rate on the thermal dependence of the magnetic entropy change ΔSM(T) and the magnetic field induced hysteresis loss through the antiferromagnetic (AFM) ↔ ferromagnetic (FM) ...
