T-MOKE for nuclear resonant reflectivity

It has been shown that transverse magneto-optical Kerr effect (T-MOKE) can be essentially enhanced in multilayers with antiferromagnetic interlayer coupling and observable even at grazing angles. The description of this effects need the application of the exact theory of reflectivity. The performed calculations show the presence of the antiferromagnetic Bragg maximum on the delayed reflectivity curve for transverse geometry which is absent in the used at present theory of Moessbauer reflectivity. The energy or time spectra of reflectivity, calculated on the basis of the exact and approximate theory, also reveal the essential difference.
