Аннотация: Thin epitaxial La1-KMnO3 films were grown using two-stage procedure. Influence of substitution of La3+ ions with K+ ions on the optical and electrical properties of La1-xKxMnO3 films (=0.05, 0.10, 0.15 0.18) has been studied in detail. A noticeable magnetorefractive effect in the films under study was detected in the infrared range. Magnetorefractive effect as well as transverse magnetooptical Kerr effect and magnetoresistance have the maximum in optimally doped sample with x=0.18 corresponding to the highest Curie temperature. The experimental data for compositions close to optimally doped films are in good agreement with the data calculated in the framework of a theory developed for manganites. The resonance-like contribution to magnetoreflection spectra of manganite films has been observed in the vicinity of the phonon bands. It is shown that magnetic and charge inhomogeneities strongly influences on the magnetooptical effects in films. Thin films of La1-xKxMnO3 with the large values of Kerr and magnetorefractive effect are promising magnetooptical material in the infrared range.
