- Abstract
For a long time, the electron paramagnetic resonance (EPR) spectrometers have been operated in X and Q bands with wavelengths of microwave radiation about 3 cm and 8 mm. Increasing the operating frequency improves the basic parameters of an EPR spectrometer. In view of this, there has recently been rapid development of high-frequency EPR spectroscopy, including the submillimeter-wave range, related to significant progress in the millimeter-and submillimeterwave technique. This paper discusses characteristic features, application areas, and the state of the art of the experimental technique of EPR spectroscopy in the millimeter-wave range and the short-wavelength region of the millimeter-wave range. The design features of the high-frequency EPR spectrometer operated in the frequency range 65–1500 GHz, which was created at the E. K. Zavoisky Physico-Technical Institute of the Kazan’ Scientific Center of the Russian Academy of Sciences, are presented. The results of studying the structure of the paramagnetic centers formed by impurity Ho3+ ions in synthetic forsterite (Mg2SiO4), obtained by the method of tunable high-frequency EPR spectroscopy, are reported.
