Preparation, Structure and Physical Properties of Fe-, Co- and Ni-rich Melt-quenched Ribbons Containing Zr or Hf

摘要

a melt-spinning technique was used to produce Te-TL alloy ribbons with TE = Zr and Hf and TL = Fe, Co or Ni for compositions around the Tl-Rich eutectic (about 90 at./100 TL content). In this part of a series of papers on these alloys, experimental results on the low-temperature magnetic properties of the Zr-Fe and Zr-Ni ribbons will be given. The ac susceptibility (Xac) data on the amorphous Zr-Fe alloys indicated the onset of magnetic ordering at T_c ≈ 200 K and the occurrence of a second magnetic tran- Sition at T_f ≈ 70 K.
