Abstract

We have investigated the X-band electron paramagnetic resonance of stoichiometric and congruent LiNbO3 crystals grown from melts doped with ∼ 500 weight ppm Fe2O3. The analysis of the observed Fe3+ spectrum for a general direction of magnetic field is complicated due to comparable magnitudes of the Zeeman and trigonal field interactions. From the observed lines with the magnetic field parallel to the c-axis and for a temperature range of 40°C < T < 300°C the three parameters in the Hamiltonian are determined to be: g = 1.995 ± 0.005D = 3B20 = (0.168 - 5.0 × 10-5T)cm-1B40 = (1.61 × 10-3 - 1.4 × 10-6T)cm-1 These parameters were found to be independent of crystal stoichiometry. © 1972.
