摘要：

The results of electron paramagnetic resonance (EPR) studies of Ce3+ impurity ions in single crystals of lead thiogallate PbGa2S4 have been reported. The Ce3+ ions substitute for Pb2+ ions in the crystal lattice of PbGa2S4. A number of paramagnetic cerium centers in lead thiogallate have been observed. The spectra are described by the spin Hamiltonian of rhombic symmetry with the effective spin S = 1/2. The g factors of the main cerium centers have been determined. A large number of paramagnetic centers are due to both nonequivalent positions of lead and local charge compensation under the substitution Ce3+ -> Pb2+.
