Notes:
Zero-field muon spin relaxation (μSR) experiments have been performed on the spin glass Fe1.75Ti1.25O5. Above the spin-glass temperature of 44 K a distinct exponential μSR rate (λ) is observed, while below Tg a square-root exponential decay occurs, indicating fast spin fluctuations. Near 8 K, a maximum in λ is indicative of transverse spin ordering. The low λ values and the sharp λ peak at Tg are very promising for the study of spin freezing models like the Vogel–Fulcher law or the power law.
