Abstract

The magnetic properties of the compound TmFeAl have been studied using57Fe and169Tm Mössbauer spectroscopy, magnetic measurements and neutron depolarization (ND). The compound exhibits a complex magnetic behaviour. At 4 K it contains a Tm moment of 7μB and a distribution of Fe moments with an average of 0.5μB. Between 10 and 60 K a distribution in magnetic ordering temperatures is observed. ND displays the growth of small magnetic domains when the temperature decreases towards 4 K. The structural disorder of the Fe atoms in the lattice combined with the competing exchange interactions between the different types of atoms and the high anisotropy of the Tm moment gives rise to the observed magnetic behaviour. Results of high field magnetization and57Fe Mössbauer spectroscopy are presented also for GdFeAl and YFeAl.
