Abstract

Mössbauer effect measurements in disordered Fe0.45Mn0.25Al0.30 alloy from 15 to 300 K show it to be a reentrant spin-glass with a freezing temperatureT K near 60 K and a Curie temperatureT c near 250 K. The Mössbauer spectra show a paramagnetic site with a relative area that increases withT and this increase is abrupt near 60 K.
