Abstract
- The magnetic cooling utilizing magneto-caloric effect is recognized as promising energy efficiency and environmentally friendly technology. Here we report a systematical study on the microstructures, magnetic properties and cryogenic magneto-caloric performances of the Gd20Ho20Tm20Cu20Ni20 amorphous ribbons. It is found that the ribbons reveal a second-order phase transition and are accompanied by a table-shaped magneto-caloric effect. The calculated magnetic-entropy-change maximum |ΔSM|, temperature averaged entropy change (i.e., TEC(10)), and refrigerant capacity reach 13.9 J/kg⋅K, 13.84 J/kg⋅K and 740 J/kg with magnetic field change of 0–7 T, respectively, indicating that the present Gd20Ho20Tm20Cu20Ni20 amorphous ribbons are good candidates for magnetic cooling.
