Magnetic characteristics of iron borate, FeBO

, film on diamagnetic gallium borate substrate were determined from electron magnetic resonance studies in the microwave frequency range of 15–36 GHz and the temperature range of 4 K to room temperature. The temperature dependence of the Dzyaloshinskii–Moriya field in the film is in accordance with that previously determined for FeBO

single crystals. In contrast, the isotropic energy gap in the film is several times larger than in the single crystal. This discrepancy has been related to deformations caused by the mismatch between the lattice parameters of the film and the substrate.
