description: This work is devoted to the study of potassium tantalate perovskite crystals doped with various impurities by the method of electron paramagnetic resonance at a frequency of 9.3 GHz. The research set the following goals: 1. Registration of EPR spectra, angular and temperature dependences in KTaO3 samples at a frequency of 9.3 GHz. 2. Calculation of g-factors, hyperfine interaction constants, analysis of the shape and width of lines at the spectrum. 3. Based on the data obtained, conclusions was drown about the nature of defects in the crystals under study. The work was carried out at the Laboratory of Microwave Spectroscopy of Crystals in the Ioffe Institute, where samples of potassium tantalate were studied using the JEOL 9.3 GHz spectrometer. The features of the EPR spectra of impurity centers of cobalt, copper and nickel in potassium tantalate crystals were analyzed. As a result, the concept of such defects in perovskite crystals was expanded.
