Oxygen-vacancy donor-electron center in Y3Al5O12 garnet crystals: Electron paramagnetic resonance and dielectric spectroscopy study

Original language description

The F+ center consisting of an electron trapped at the oxygen vacancy (V_O) was investigated in the oxygen deficient Y3Al5O12 (YAG) garnet crystals by electron paramagnetic resonance (EPR) techniques. The measurements were performed in the wide temperature interval 5450 K and the frequency range 9.4350 GHz using both the conventional continuous-wave and pulse EPR experiments. The pulse electron-nuclear double resonance was applied to resolve the hyperfine interaction of the trapped electron with surrounding nuclei. A model of the F+ center in YAG is proposed on the basis of the obtained experimental data. The model assumes localization of an electron within oxygen vacancy space at T < 50 K, like in MgO, and its further behavior with temperature increase is similar to that of the donor electron in a semiconducting material.n
