Аннотация:Single crystals of K1-xTi1-xNbxOPO4 and K1-xTi-1xSbOPO4 solid solutions are grown and their dielectric properties, electrical conductivity, and nonlinear optical properties are studied. Maximal content of these dopants x is found to be 0.11 for Nb and 0.23 for Sb. This doping leads to the creation of the additional potassium vacancies and the high ionic conductivity sigma(33). Ferroelectric phase transitions become more diffuse and their temperature decreases. All the crystals show intensive broad maxima of the dielectric permeability attributed with the relaxation phenomena. (C) 2003 American Institute of Physics.
