Mössbauer reflectivity is the very effective method for magnetization depth profile investigations. Specific polarization dependence of the nuclear resonant scattering amplitude on the hyperfine field orientation predetermines the importance of the polarization analysis of the reflected radiation for magnetic structure determination. The first experiment with selection of the rotated π→σ’ Mössbauer reflectivity has been performed [1] at the ID18 beamline of the ESRF making use of the π-polarized radiation from Synchrotron Mössbauer Source (SMS). The new approach has interesting perspectives for investigations of surfaces, ultrathin layers and multilayers having complicated magnetic structures.
