Abstract

Rotation of the Fe magnetic moments toward the collinear state in applied magnetic fields up to 7 T was studied by Fe57 Mössbauer spectroscopy at 4.2 K. The investigated Fe100-xZrx (7≤x≤12) amorphous alloys show spin glass, reentrant spin glass, and ferromagnetic behavior at different concentrations. The collinear state was reached in all the alloys below 7 T. Large high field susceptibilities corresponding to more than 0.1B increase of the average Fe magnetic moments were deduced from the hyperfine fields. The results are in good agreement with bulk magnetic measurements and cannot be explained by antiferromagnetically aligned Fe moments.
