摘要
Several categories of disordered ferroelectrics and antiferroelectrics are described. Using examples of materials studied recently in our laboratory, the manifestation of disorder in the infrared and microwave spectra is demonstrated, The following single crystals and/or ceramics and/or glasses are discussed: (NH4)(2)SO4, AgNbO3, Pb(Sc1/2Ta1/2)O-3, PLZT 9.5/65/35 and LaBGeO5.
