Grazing incidence nuclear resonant scattering of synchrotron radiation
(synchrotron Mössbauer reflectometry) has recently been efficiently
applied to study the magnetic structure of multilayers. Principles and
recent experiments of synchrotron Mössbauer reflectometry are briefly
reviewed. The orientation of the layer magnetization in an
antiferromagnetically coupled multilayer is determined both from
time-integral and time-differential specular synchrotron Mössbauer
reflectometry experiments. Spin-flop phenomena are studied. Off-specular
(diffuse) scattering gives information on the in-plane antiferromagnetic
domain structure.
