Mössbauer and magnetic susceptibility experiments at temperatures down to 4.2°K and in external fields up to 140 kOe show orthorhombic Al2−xFexO3 (0.61.6Fe0.4O3 is paramagnetic above 80°K, and at 4.2°K exhibits a Mössbauer spectrum characteristic of a nonunique hyperfine field; the application of an external magnetic field produces a spectrum with an enhanced Δm=0 line which suggests a canted spin structure similar to that in the high‐temperature phase (T>260°K) of αFe2O3.
