Abstract:
Electron paramagnetic resonance (EPR) spectra of a GdMnO3/SrTiO$_3$ thin film in the $X$ band have been measured in the temperature interval from $200$ to $450$ K. Signals from two types of paramagnetic centers have been observed in the spectra. The first paramagnetic center is a subsystem of Gd$^{3+}$ ions, in the EPR spectrum of which the fine structure lines are resolved below $350$ K. The second paramagnetic center is a system of manganese and gadolinium ions, in the EPR spectrum of which an exchange-narrowed line is observed with the width $\Delta H$ several times less than the width $\Delta H$ of an exchange-narrowed line observed in the GdMnO$_3$ single crystal. Unusual magnetic properties are due to the mismatch of the lattice parameters of the GdMnO$_3$ thin film and the SrTiO$_3$ substrate.
