A possibility of use of the controlled decomposition of solid solutions of oxides with perovskite structure in the state of coexisting domains of the antiferroelectric (AFE) and ferroelectric (FE) phases for manufacturing of materials with negative refractive index is demonstrated. The lead zirconate titanate based solid solutions are considered as an example of substances suitable for creation of such materials. Manufactured composites constitute a dielectric matrix with a structure of conducting interphase boundaries separating domains of the FE and AFE phases. The electric conductivity of interphase boundaries occurs as a result of the local decomposition of solid solutions in the vicinity of these boundaries. The process of local decomposition and consequently the interphase boundaries conductivity can be controlled by means of external influences.
