Near-Surface Structural Phase Transition of SrTiO $_{3}$ Studied with Zero-Field $β$ -Detected Nuclear Spin Relaxation and Resonance

arXiv:cond-mat/0511526 · doi:10.1103/PhysRevLett.96.147601

Abstract

We demonstrate that zero-field $β$ -detected nuclear quadrupole resonance and spin relaxation of low energy $^{8}$ Li can be used as a sensitive local probe of structural phase transitions near a surface. We find that the transition near the surface of a SrTiO $_{3}$ single crystal occurs at $T_{c} \sim 150$ K, i.e., 45 K higher than $T_{c}^{b u l k}$ , and that the tetragonal domains formed below $T_{c}$ are randomly oriented.
