Understanding muon diffusion in perovskite oxides below room temperature based on harmonic transition state theory

T. U. Ito, W. Higemoto, K. Shimomura

In positive muon spin rotation and relaxation (${\mu }^{+}$SR) spectroscopy, positive muons (${\mu }^{+}$) implanted into solid oxides are conventionally treated as immobile spin-probes at inter…
