Abstract:
The magnetorefractive effect is studied in the infrared spectral region of 2-13 mu m in molecular-beam epitaxy-grown {[}Fe(t(Fe), angstrom)/Cr(10 angstrom)](n) superlattices. The Fe layer thickness varies from 15.3 to 7.2 angstrom. The effective dielectric function epsilon(eff) and the giant magnetoresistance were measured on the same samples. Relaxation times tau(up arrow(down arrow))(i) and scattering probabilities P(i)(up arrow(down arrow)) of conduction electrons at interfaces, as well as spin asymmetry coefficient gamma(Fe/Cr(100)) were obtained from the magnetoreflection in the intraband absorption region. The experimental estimations of the scattering parameters of conduction electrons are compared with the available results of theoretical calculations.
