INFLUENCE OF FERRITES PHASE ON PROPERTIES OF THE BARIUM ZIRCONIUM TITANATE BASED MULTIFERROIC COMPOSITES
Апстракт
Multiferroic composites with general formula Ba(Ti0.95Zr0.05)O3–Ni0.7Zn0.3Fe2O4/
CoFe2O4/Ni0.7Cu0.01Sm0.05Zn0.29Fe1.95O4, (BTZr(95-5)–NZF/CF/NCuSmZF) were
prepared by mixing chemically obtained different types of ferrites and BTZ(95-5)
powders in the planetary mill for 24 h. The optimization of sintering process was
performed and powders were pressed and sintered at 1300 °C for obtained composites
samples. From X-ray analysis for single phase and composites ceramics can be noticed
the formation of crystallized structure of ferrites and barium zirconium titanate. SEM analyses indicated the formation of two types nanosized grains, polygonal ferromagnetic
and rounded ferroelectric grains.
The electrical properties of these materials were investigated using impedance
spectroscopy and analysis of ferroelectric measurements. Impedance analysis of all
investigated samples has shown different relaxation processes that originated from the
grain and grain boundary contributions. The r...esults of polarization vs. electric field
measurements have shown the influence of magnetic phase type and its concentration on
the ferroelectric properties of the composites. Due to high conductivity of ferrite phases
and presence of interfacial polarization, the shapes of these curves differed from the
conventional ferroelectric materials.
