Abstract: A high-frequency electron paramagnetic resonance spectrometer with frequency modulation has been developed. Advantages of the applied method for recording spectra of paramagnetic centers with giant fine-structure splittings are demonstrated by the example of non-Kramers ions in a garnet crystal.

Keywords: electron paramagnetic resonance, EPR spectrometer, frequency modulation, spin, fine structure.
