    Bibliographic description in the original language Electron paramagnetic resonance studies of GdMnO3 single crystal and thin film deposited onto a LaAlO3 substrate. // Yatsyk I.V., Mamedov D.V., Fazlizhanov I.I., Gavrilova T.P., Eremina R.M., Andreev N.V., Chichkov V.I., Mukovskii Ya.M., Krug von Nidda H.-A., and Loidl A. // JETP Letters. - 2012. - V. 96, № 6. - P. 416-420.
    Annotation Electronic paramagnetic resonance (EPR) spectra of a GdMnO3 single crystal and GdMnO3/LaAlO3 thin film have been measured at X and Qband frequencies in the temperature range from 4.2 to 300 K. It is found that the EPR spectrum of a GdMnO3 single crystal consists of only one broad exchangenarrowed line. Unusual magnetism is observed at the interface between the GdMnO3 thin film and LaAlO3 substrate, where it is possible to see the fine structure of the EPR spectrum for a Gd3+ ion. The parameters characterizing the fine structure related to the Gd3+ ion in the GdMnO3 film deposited onto the LaAlO3 substrate are determined.
