A study of low-frequency relaxation of polarization in conventionally prepared ceramic compounds of (1-x)(K 0.5 Na 0.5 )(Nb 0.93 Sb 0.07 )O 3 +xBaTiO 3 +0.5mol.%MnO 2 (x = 0.02, 0.04) examined over a wide temperature range is reported. Anomalous behavior of the temperature dependence of the coercive field E c (T) is detected in the temperature range of the orthorhombic to tetragonal phase transition. The observed features of polarization are assigned to dynamics of the domain structure at the temperature range of phase coexistence.
