Abstract
Mösbauer spectroscopy, magnetization, susceptibility, and neutron depolarization have been used to investigate the loss of long-range ferromagnetic order in a-Fe90−xRuxZr10. Our depolarization results show a rapid reduction in domain size from 1.6 to 0.4 μm as x increases from 0 to 2, with no evidence for long-range order in either depolarization or magnetization data for x⩾3. Furthermore, for x=1 and 2, we observe a clear break in the temperature dependence of 〈Bhf〉 which may be associated with ordering of transverse spin components in these partially frustrated alloys.
