| Binary SrCu0.33Ta0.67O3-Co1-xMnxFe2O4 (SCTO-(C,M)FO) multilayer composites were investigated by X-ray diffraction, impedance spectroscopy, and DC conductivity measurements. It was established that all synthesized compounds adopted the tetragonal symmetry P4mm and cubic symmetry Fd̅3m for SCTO and mixed (C,M)FO ferrite system, respectively. The numerously electrochemical processes have been isolated from the impedance and electric modulus formalisms as phenomena responsible for a transport of electric charge in various regions of multilayer composite. This result indicates an electrically inhomogeneous SCTO-(C,M)FO materials both morphologically (grain boundary regions) and structurally (interfacial regions). Also, the energy activations EA of 0.6÷0.8 eV have been found from the Arrhenius plots, whose values are typical for electroceramic materials. |
