Abstract In this paper, the glass forming ability (GFA), magnetic properties and magneto-caloric effect (MCE) performances in Er0.2Tm0.2Ho0.2Cu0.2Co0.2 amorphous ribbon were reported. A relatively big supercooled liquid region ~43.1 K and a broad typical ferromagnetic to paramagnetic phase transition around TC ~ 13.5 K accompanied by a large cryogenic MCE were observed in Er0.2Tm0.2Ho0.2Cu0.2Co0.2 amorphous ribbon. The magnetic entropy change peak and refrigerant capacity (relative cooling power) values in Er0.2Tm0.2Ho0.2Cu0.2Co0.2 amorphous ribbon for ΔH = 0–5 T are calculated to be 15.73 J/kgK and 354.3 (448.1) J/kg, respectively. The large MCE parameters together with good GFA, making the Er0.2Tm0.2Ho0.2Cu0.2Co0.2 amorphous ribbon is also attractive for cryogenic magnetic refrigeration (MR).

摘要 本文报道了Er0.2Tm0.2Ho0.2Cu0.2Co0.2非晶薄带的玻璃形成能力（GFA）、磁性能和磁热效应（MCE）性能。在 Er0.2Tm0.2Ho0.2Cu0.2Co0.2 非晶带中观察到相对较大的过冷液体区域 ~43.1 K 和在 TC ~ 13.5 K 附近广泛的典型铁磁到顺磁相变，伴随着大的低温 MCE。Er0.2Tm0.2Ho0.2Cu0.2Co0.2 非晶带在 ΔH = 0-5 T 时的磁熵变峰值和制冷剂容量（相对冷却功率）值计算为 15.73 J/kgK 和 354.3 (448.1) J/公斤，分别。大的 MCE 参数和良好的 GFA，使得 Er0.2Tm0.2Ho0.2Cu0.2Co0.2 非晶带对低温磁制冷 (MR) 也很有吸引力。
