The main value of g-factors along principal local axes was determinate. The two nonequivalent Yb3+ centers were found in ac-plane. It is shown that local symmetry of Yb3+ ion in ac-plane is not higher than rhombic. Some peculiarities in the frequency-field dependence of an absorption line was found in H|| b orientation.Materials Sciencetext
