Abstract The surface magnetic ordering of an α-57Fe2O3 and 57FeBO3 single crystal was studied by Depth Selective Conversion Electron Mössbauer Spectroscopy (DCEMS). The depth selective Mössbauer data of 57FeBO3 up to the Néel temperature (T N = 348.35 K) reveal the coexistence of the canted antiferromagnetic bulk phase and a magnetic surface phase that shows time relaxation. Both phases are separated by a wall (interim layer) and the thickness of the magnetic surface layer increases as the crystal is heated to T N.
