AB  - Composites based on barium titanate and nickel zinc ferrite doped with cooper and samarium were prepared by a mixing method. The formation of barium titanate tetragonal crystal structure and nickel zinc ferrite cubic spinel structure was identified. Polygonal grains were formed in all three types of ceramics. Due to the very high conductivity of ferrite phase in the materials the ferroelectric hysteresis loops were roundish and not typical for classical ferroelectric material. The break down field was found to be similar for all compositions. Leakage current measurements have shown the existence of different types of conductivity mechanisms in each material. The impedance analysis suggested a bit stronger impact of grain boundaries on total conductivity of the composites and the mechanism of polaronic conduction of two types. The magnetization of the composites is lower than for the pure ferrite phase and corresponds to the weight fraction of the ferrite phase. The soft magnetic nature of these composites might be very useful for development of multifunctional devices which will be able to switch the magnetization with small external magnetic field. Humidity sensing properties of the prepared ceramics were also investigated.

AB  - In this paper the fabrication of BaTiO3-based thin film heterostructures with ring silver electrodes by low cost deposition techniques was investigated. BaTiO3, Ba1-xSrxTiO3 (x = 0.1, 0.2, 0.3, 0.4) and BaTi1-xZrxO3 (x = 0.1, 0.2) thin films for potential application in microwave technologies were prepared by chemical solution deposition method on Pt-coated silicon substrates and sintered at different temperatures. The prepared films were examined by SEM, AFM, XRD and Raman spectroscopy in order to study the influence of dopants on microstructure and phase changes. Dielectric and ferroelectric properties of the doped BaTiO3 thin films were also investigated to find the optimal composition and structure for tunable application. Complex shaped silver electrodes suitable for measurements of tunability at GHz frequencies were prepared by inkjet printing method. The electrodes with circular shape were printed on the surface of BaTiO3 based thin films by Dimatix inkjet printer. Precision limits of the method and the influence of printing conditions on electrode size and quality were also investigated.
