Abstract

Magnetic, Mössbauer, and neutron diffraction measurements were used to study the anomalous magnetic behavior of Fe Al2. The magnetization is almost linear with the applied field up to 14 T at 5 K. The Fe-Al system Mössbauer measurement in the 7 T external magnetic field clearly shows the presence of canted, antiferromagnetically coupled Fe magnetic moments. Neutron diffraction indicates an incommensurate magnetic structure with a periodicity of about 1.1 nm.
