Fabrication and Study of GdMnO3 Multiferroic Thin Films

Laboratory technology of GdMnO3 thin film fabrication was elaborated. Samples of GdMnO3 were fabricated at NdGaO3 substrate by magnetron sputtering using off-axis scheme. Structure and phase content of the samples obtained were studied as well as their magnetic properties. The surface topography of the films was observed by atomic force microscopy. Presence of peculiarities at the temperature dependences of magnetic susceptibility points at magnetic phase transitions in GdMnO3, which were found before in the single crystals. This fact jointly with X-ray data shows that at definite fabrication regimes one can obtain the multiferroics thin film GdMnO3 modification, and the film quality permits to carry out accurate study of the compound in question.
