Abstract
Abstract
We report the β-detected NMR of implanted 8Li+ in the rhombohedrally distorted perovskite LaAlO3. As observed in other insulating perovskites, the resonance has large quadrupolar splitting. However, it exhibits additional splitting due to the rhombohedral distortion. In addition, the magnitude of the electric field gradient at the 8Li site is larger than in cubic perovskites, such as SrTiO3, with vQ ≈ 191.3 kHz.
