Abstract:

Spectral investigations of magnetorefractive effect (MRE) have been performed in p-polarized light in the range of wavelengths lambda = 2-13 mu m using a series of Fe/Cr superlattices with a variable thicknesses of iron and chromium layers grown by the method of molecular-beam epitaxy. The same samples have been used to measure the magnetization and the magnetoresistance. Based on an analysis of the MRE spectra, the parameters of the interfacial spin-dependent scattering of conduction electrons (effective relaxation times tau (i) (a dagger(a dagger{''})) , spin asymmetry coefficient gamma(Fe/Cr(100)), and scattering probabilities P (i) (a dagger(a dagger{''})) ) have been determined in terms of the magnetoreflection theory for multilayer structures with different thicknesses of chromium layers. It has been found that the changes in the parameters of the interfacial scattering of conduction electrons occur with increasing chromium-layer thickness primarily in the (a dagger{''})-current channel.
