摘要: Critical anomalies in the ${\mathrm{Mn}}^{2+}$ impurity spectra near ferroelectric phase transition tris-sarcosine calcium chloride (TSCC) crystals have been interpreted terms of a collective fluctuation polar pseudospin system representing Ca(sarcosine${)}_{6}$ complexes lattice. The anomalous line broadening paraelectric was found to be closely related splitting below temperature ${T}_{c}$. At temperatures close ${T}_{c}$ shape asymmetrical, indicating that sinusoidally distributed pseudospins were randomly sampled by impurities. time scale EPR measurements modified shape, where presence slow between pair lines evident. Contrary recent spectroscopic and dielectric results on TSCC crystals, critical well resolved give grounds for order-disorder dynamics transition.
