Abstract: In order to clarify the nature of the additional phase transition at H 1 ( T ) 〈 H c ( T ) of the layered antiferromagnetic (AF) insulator FeBr 2 as found by Aruga Katori et al. (1996) we measured the intensity of different Bragg-peaks in different scattering geometries. Transverse AF ordering is observed in both AF phases, AF I and AF II. Its order parameter exhibits a peak at T 1 = T ( H 1 ) in temperature scans and does not vanish in zero field. Possible origins of the step-like increase of the transverse ferromagnetic ordering induced by a weak in-plane field component when entering AF I below T1 are discussed.
