Description
Evolution of optical, magnetooptical, and transport properties of La1-xAgxMnO3/SrTiO3 epitaxial films depending on the silver concentration (x = 0.05, 0.10, 0.15, and 0.25) is studied. The highest values of the Curie temperature (TC ∼ 317 K), magnetoresistance (∼16%), magnetotransmission (∼8%), and transverse Kerr effect (δ ∼ 20 x 10-3) are attained for a concentration x = 0.10 of Ag+ ions. Comparison of the temperature dependences of the transmission of IR radiation, resistivity, magnetotransmission, magnetoresistance, and Kerr effect indicates electronic and magnetic inhomogeneity of the films in spite of saturation of films with silver. This feature of the film state is explained using the concepts of epitaxial stresses and metastable point defects
