Abstract:

The electron paramagnetic resonance (EPR) spectra of Eu2+ impurity centers in SrMoO4 crystals have been studied in the temperature range of 1.8, 100-300 K. A hyperfine structure has been simulated for Eu-151,Eu-153 of different EPR transitions observed experimentally at different temperatures and external magnetic field orientations. A unique set of all parameters of the spin Hamiltonian for the known sign of the hyperfine interaction parameters A (i) has been determined. It has been found that the diagonal parameters |b (n) (0) | of the spin Hamiltonian decrease with increasing temperature; however, the parameter b (4) (4) increases. The results of the study have demonstrated that |b (2) (0) (T)/P (2) (0) (T)| similar to const for Eu-151,Eu-153 in this single crystal.
