Abstract Multiferroic BiFeO δ ( δ =2.67, 2.95 and 3.02) compound of various oxygen contents ( δ ) have been prepared by gel sol method. The influence of oxygen contents on the structure, electric and magnetic properties of BiFeO 3 compound has been investigated. X-ray diffraction (XRD) measurements indicate that all the samples of BiFeO δ have the same crystal structure regardless of oxygen content. The SEM micrograph reveals microstructures comprising of grains with various sizes from 200 nm to...

Multiferroic Bi0.95Dy0.05Fe1-xCoxO3 (x=0, 0.05, 0.1, 0.15) ceramics were prepared by rapid liquid phase sintering method. We studied the effect of (Dy+Co) doping on the structure, electrical and ferromagnetism properties of BiFeO3 ceramics. The structure and morphology of BiFeO3 ceramics were characterized by X-ray diffraction (XRD) and scanning electron microscopey (SEM). The results showed that all the peaks for Bi0.95Dy0.05Fe1-xCoxO3 samples can be indexed based on the crystal structure of pu...

Ni/silicone rubber composites with nickel powders of different particle sizes were prepared at a filler/ silicone rubber mass ratio of 2.4∶1.0.The piezoresistivity and the dielectric properties of the composite samples at room temperature were measured.The mechanism of electric conduction is discussed together with the SEM images of the samples.The results show that piezoresistivity of Ni/silicone rubber composite is enhanced by reducing the filler particle size: at low pressures,the pressure de...

The influence of oxygen content on the dielectric property of BiFeO3 ceramics is studied by experiment and first-principles calculation. The experimental result demonstrates that the dielectric constant of BiFeO3 is strongly dependent on introduced oxygen and oxygen vacancies. By comparison with BiFeO3, the introduced oxygen and oxygen vacancies can lead to a reduction in dielectric constant of BiFeOδ at a lower frequency. The first-principles calculation also shows a similar result when photon ...

Tungsten oxide films were deposited on ITO coated glass substrates by reactive DC magnetron sputtering.The electrochromic(EC) properties of the films were studied with different target-substrates distance in the deposition process.The WO3 films were characterized with X-ray diffraction(XRD),X-ray photoelectron spectroscopy(XPS) and scanning electron microscopy(SEM).The electrochromic properties and mechanism were discussed by means of spectrophotometry.It indicates that the samples are amorphous...
Polycrystalline YBa2Cu3O6.13 ceramics were prepared by solid state reaction.Temperature dependence of dielectric constant of this oxygen-deficient YBCO sample was measured in the frequency range from 100Hz to 1MHz with a HP4294A precision impedance analyzer.An abnormal dielectric behavior was observed in the vicinity of antiferromagnetic phase transition,which is attributed to the induced ferroelectric transition.In addition,room temperature ferroelectric hysteresis loops of the YBCO ceramics we...
