Grazing incidence nuclear resonant scattering of synchrotron radiation can
be applied to perform depth-selective phase analysis and to determine the
isotopic and magnetic structure of thin films and multilayers. Principles
and recent experiments of this new kind of re-flectometry are briefly
reviewed. Methodological aspects are discussed. Model calculations
demonstrate how the orientations of the sublattice magnetisation in ferro-
and antiferromag-netic multilayers affect time-integral and time-differen
tial spectra. Experimental examples show the efficiency of the method in
investigating finite-stacking, in-plane and out-of-plane anisotropy and
spin-flop effects in magnetic multilayers.
