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 2gx 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.
