摘要

本文报道了57Fe Mössbauer对Fe90Zr10合金的磁浓缩非晶态测量结果，首次证明了Tf = 35 K低温磁化异常的微观来源。这表现在平均超细磁场Bhf(T)在Tf以下的异常增加，类似于在接近渗透阈值的浓度范围内观察到的晶体和非晶自旋玻璃合金。

Local evidence for re-entrant magnetic behaviour in amorphous Fe90Zr10 alloys

We report results of ⁵⁷Fe Mössbauer measurements on the magnetically concentrated amorphous Fe₉₀Zr₁₀ alloy which give the first evidence of a microscopic origin for the low temperature magnetization anomaly at T_f = 35 K. This is shown by an anomalous increase in the average magnetic hyperfine field $B_{hf} (T)$ below T_f, similar to that observed in crystalline and amorphous re-entrant spin-glass alloys in the concentration range near the percolation threshold.
