Thermally induced correlation decays, averaged over different starting temperature intervals (A) T1 = 410–443 K in the monoclinic (M) phase. (B) T1 = 460–482 K in the M phase. (C) T1 = 590–650 K in the tetragonal (T) phase. Symbols are experimental results, and solid lines are the fits to Eq. 2 with the best-fit parameters indicated.
