Abstract
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 Tf = 35 K. This is shown by an anomalous increase in the average magnetic hyperfine field below Tf, similar to that observed in crystalline and amorphous re-entrant spin-glass alloys in the concentration range near the percolation threshold.
