研究了快凝非晶态RE(70)Tm(30)(RE=Gd，Tb，Dy，Ho和Er；Tm=Fe和Ni)和Gd65Co35合金作为潜在的磁制冷剂的磁性能和变场比热。在5K至有序温度范围内，所有Gd-Tm合金的磁滞回线基本为零。RE(70)Tm(30)合金的矫顽力主要取决于稀土的种类，并按RE=Gd的顺序增大
The magnetic properties and field-dependent specific heat of melt-spun amorphous RE(70)TM(30) (RE=Gd, Tb, Dy, Ho and Er; TM=Fe and Ni) and Gd65Co35 alloys were investigated as potential magnetic refrigerants. Essentially zero magnetic hysteresis was observed in all the Gd-TM alloys at temperatures from 5 K up to the ordering temperatures. The coercive force of the RE(70)TM(30) alloys depended mainly on the RE species and increased according to the order of RE=Gd
