Title: Dielectric and magnetoelectric properties of (x)Ni{sub 0.8}Co{sub 0.1}Cu{sub 0.1}Fe{sub 2}O{sub 4}/(1 - x)PbZr{sub 0.8}Ti{sub 0.2}O{sub 3} composites

Abstract

Ceramic composites of Ni{sub 0.8}Co{sub 0.1}Cu{sub 0.1}Fe{sub 2}O{sub 4} and lead-zirconate-titanate (PZT) were prepared using conventional solid state reaction method. The presence of constituent phases in composites was confirmed by X-ray diffraction (XRD). The variation of dielectric constant with frequency (100 Hz-1 MHz) and temperature has been studied. The variation of loss tangent (tan {delta}) with temperature (at frequency 1 kHz) has also been studied. The magnetoelectric (ME) output was measured as a function of dc magnetic field. The maximum value of ME output (625 mV/cm) was observed for 25% ferrite + 75% ferroelectric phase. The maximum ME response can be explained in terms of the content of ferrite, permittivity of dielectric material and the intensity of magnetic field. The ME response of these composites was observed to be linear within low dc magnetic field. These composites may form the basis for the development of magnetic sensors and transducers for use in solid state microelectronics and microwave devices.

  • The structural, electrical, dielectric, magnetic and magnetoelectric properties of (x)Ni{sub 0.8}Zn{sub 0.2}Fe{sub 2}O{sub 4} + (1 - x)Pb{sub 0.93}La{sub 0.07}(Zr{sub 0.60}Ti{sub 0.40})O{sub 3} (x = 0, 0.15, 0.30, 0.45 and 1) have been studied by means of various experimental techniques. Polycrystalline samples of this series have been prepared by the double sintering ceramic method. X-ray diffraction data analysis revealed purity of the composites. Microstructural analysis using scanning electron microscopy mode depicts the presence of two phases in contact with each other. Dielectric properties were studied at and well above room temperature. Temperature dependent variation of the dielectric constant show diffusedmore » phase transition which can be well described by fitting the Lorentz-type relation, {epsilon}{sub A}/{epsilon}=1+(T-T{sub A}){sup 2}/2{delta}{sub A}{sup 2}. Observation of well-saturated ferroelectric hysteresis loop and magnetic hysteresis loop for composites indicates that ferroelectric and magnetic ordering exist simultaneously at room temperature. The static value of magneto electric voltage coefficient ({alpha}{sub E}) has been studied as a function of magnetic field at room temperature for all the composites. The maximum value of {alpha}{sub E} is 7.53 mV/(cm Oe) for 85% PLZT-15% NZFO composites.« less

X-ray diffraction analysis and field emission secondary electron microscopy have been used for structural and morphological analysis, respectively. The spinel CoFe{sub 2}O{sub 4} and perovskite 0.5Ba(Zr{sub 0.2}Ti{sub 0.8})O{sub 3}–0.5(Ba{sub 0.7}Ca{sub 0.3})TiO{sub 3} phase could be identified in the composites. Two anomalies in dielectric constant have been identified: first one is close to ferroelectric to paraelectric phase transition of 0.5Ba(Zr{sub 0.2}Ti{sub 0.8})O{sub 3}–0.5(Ba{sub 0.7}Ca{sub 0.3})TiO{sub 3} ceramic and the other lies near the magnetic transition temperature of CoFe{sub 2}O{sub 4}. There is an increase in magnetocapacitance and saturation magnetization of the composites at room temperature with increase in CoFe{sub 2}O{sub 4} content. The magnetoelectric coupling coefficient (γ) was approximated by Δϵ ∼ γM{sup 2} relation. The optical band gap energy of the composites decreases with increase in CoFe{sub 2}O{sub 4} content.« less
  • Ni{sub 0.50}Co{sub 0.50}Fe{sub 2}O{sub 4} + Ba{sub 0.8}Pb{sub 0.2}TiO{sub 3} composites were prepared using a conventional ceramic double-sintering method. The phase analysis carried out by X-ray diffraction technique has confirmed that no intermediate or impurity phase is present in all the composites prepared. The dc resistivity, thermo emf studied as a function of temperature and ac conductivity ({sigma}{sub ac}) investigated in the frequency range 100 Hz-1 MHz have concluded that the nature of conduction in the present composites is due to small polaron. The value of static magnetoelectric conversion factor, i.e. dc (ME){sub H} studied as a function of magneticmore » field is very low and cannot be-fit any practical application, but is essential to be reported as present communication informs that the conductivity of the samples and nature of conduction adversely affect the magnetoelectric conversion factor.« less
