Abstract

The novel FeCeB (x = 5, 6, 7) metallic glass (MG) ribbons were fabricated in this work. The compositional dependence of glass forming ability (GFA), magnetic and magnetocaloric properties of these ternary MGs, and the mechanism involved was investigated. The GFA and Curie temperature () of the MG ribbons were found to improve with the boron content, and the peak value of magnetic entropy change (-Δ) reaches a maximum of 3.88 J/(kg × K) under 5 T when x = 6. Based on the three results, we designed an amorphous composite that exhibits a table-shape magnetic entropy change (-Δ) profile with a rather high average -Δ (-Δ~3.29 J/(kg × K) under 5 T) from 282.5 K to 320 K, which makes it a potential candidate for the highly efficient refrigerant in a domestic magnetic refrigeration appliance.

摘要

在本工作中制备了新型的FeCeB（x = 5、6、7）金属玻璃（MG）薄带。研究了这些三元金属玻璃的玻璃形成能力（GFA）、磁性和磁热性能的成分依赖性以及其中涉及的机制。发现MG薄带的玻璃形成能力和居里温度随硼含量的增加而提高，当x = 6时，磁熵变（-Δ）的峰值在5 T下达到最大值3.88 J/（kg×K）。基于这三个结果，我们设计了一种非晶复合材料，其在282.5 K至320 K范围内呈现出具有相当高的平均-Δ（在5 T下-Δ~3.29 J/（kg×K））的平台形磁熵变（-Δ）曲线，这使其成为家用磁制冷设备中高效制冷剂的潜在候选材料。
