Abstract

Electron Spin Resonance and optical absorption spectra of trivalent vanadium in Y₃Al₅O₁₂ crystals before and after (gamma) -irradiation and thermal annealing treatments are reported. The observed spectra are interpreted as arising from octahedrally coordinated V³⁺(3d²) ions. We obtained Lande factor 2g_x equals 2.237, and hyperfine structure constant A_(parallel) equals 330 X 10^-4 cm^-1 for T equals 4 K. It is possible to obtain tetrahedrally coordinated V³⁺ ions using annealing of YAG:V crystal in reducing atmosphere.
