Abstract
The site location of ions in congruent strontium barium niobate has been systematically investigated by means of low-temperature optical and electron paramagnetic resonance spectroscopies. The experimental results obtained by these complementary techniques clearly indicate that ions are mainly located in only one of the four available cationic sites, the A2 sites, and preserving the local symmetry of these host cation sites. The energy levels and -factor value experimentally obtained by both techniques have been used to calculate the crystal field parameters for the ions in this A2 cationic site.
