Abstract

We have measured the temperature dependence of the β-NMR resonances of ⁸Li⁺ implanted in the top few thousand Å of a crystal of SrTiO₃ in a magnetic field of 3 T||〈100〉. A well-resolved quadrupolar splitting of the resonance is observed indicating a noncubic Li site with 〈100〉 symmetry and a quadrupolar frequency ν_Q(211 K) = 153.2(4) kHz. The cubic-to-tetragonal phase transition is reflected in the linewidths demonstrating that β-NMR is a sensitive probe of the structure near a surface.
