Abstract

After ball-milling nonmagnetic FeAl a grain structure resembling to a rigid magnetic foam is indicated by Mössbauer spectroscopy. It consists of nanosize nonmagnetic grains with ferromagnetic boundaries formed by about two atomic layers of Fe. The magnetic behavior is uncommon: (i) the transition to the paramagnetic state is glass-like and magnetic relaxation sets in at low temperatures; (ii) the magnitude of the local Fe magnetic moments decreases linearly with temperature; (iii) in high fields a strongly anisotropic ferromagnetic behavior is observed.
