We have studied the influence of initial domain structure on piezoelectric and dielectric properties of Sr 0.61 Ba 0.39 Nb 2 O 6 single crystals slightly doped with Ce and Ni. Initial domain structure was created by zero-field cooling, in-field cooling, and partial switching. The difference in the frequency dependences of macroscopic piezoelectric response and temperature dependences of dielectric permittivity for various initial domain structures was revealed. © 2018 Institute of Physics Publishing.
