AbstractDual relaxation processes have been observed in a straightforward way by photon correlation spectroscopy (PCS) for polarization clusters in barium titanate during paraelectric-ferroelecric phase transition. The observed fast relaxation process for polarization clusters covers a broad temperature region and exhibits an anomaly near the Curie temperature (T-C). The slow relaxation process occurs at 4 K above T-C and covers a limited temperature region, where the relaxation time exhibits an approximately linearly decreasing behavior. This study provides deep insight into the complex phase transition of barium titanate. (c) 2015 The Japan Society of Applied Physics
