Mössbauer spectra of bernalite, a recently described mineral with a distorted perovskite-type structure and chemical formula Fe(OH) 3 , were recorded at 4 K in external magnetic fields up to 6 T to obtain information about the magnetic structure. Spectra show a single hyperfine magnetic component, where the angle between the net magnetic moment and the direction of the external field is close to 90°. The most likely spin arrangement is a slight deviation from a collinear antiferromagnet, resulting in a weak ferromagnetic moment.
