“…It is found that the value of the n vary between 0 and 1 (0 B n B 1) depending on temperature. This suggests that the electrical conduction in the materials are also due to thermally activated process [29,30]. The ac conductivity is found to increase with increase in both frequency as well as Dy concentration.…”

The ac impedance and conductivity properties of Dy doped Bi 4 V 2 -x Dy x O 11 (x = 0.05, 0.10, 0.15 and 0.20) ceramics prepared by solid-state reaction technique, in a wide frequency range at different temperatures have been studied. All the samples exhibited b-type phase orthorhombic structure at room temperature. The Nyquist plot confirmed the presence of both grain and grain boundary effects for all Dy doped samples. Double relaxation behavior was also observed. The grain and grain boundary resistance decreases with rise in temperature for all the concentration and exhibits a typical negative temperature co-efficient of resistance (NTCR) behavior. An analysis of the electric modulus suggests the possible hopping mechanism for electrical transport processes of all the materials. The ac conductivity spectrum obeys Jonscher's universal power law. DC conductivity of the materials were also studied and values of the activation energy found to be 0.40, 0.49, 0.73 and 0.78 eV for the compositions x = 0.05, 0.10, 0.15 and 0.20, respectively, at different temperatures (150-375°C).

“…As shown in Table 1, there is a good agreement between the calculated lattice parameters and its theoretical values from ICDD cards. There is a small deviation in lattice parameters of nanocomposite Bi FeO 3 /Ni 0.1 Fe 2.9 O 4 , which may be related to minor distortion induced to sample or essential phases exerted stress on each other during singlephase mixing [16]…”

These materials have gained great attention for numerous applications as electronics [14], memory devices [15], sensors [16] and switches [17]. Magnetoelectricity in single-phase compounds displays intrinsic magnetoelectric coupling because of its homogeneity and chemically isotropic.…”

The import marvel in multiferroic substances is the existence of spontaneous polarization and magnetization which enable these materials meet the needs of technological applications. Multiferroic of BiFeO3 and nickel-doped magnetite was synthesized separately by flash and co-precipitation methods, respectively. The two phases were confirmed by X-ray diffraction (XRD), scanning electron microscope (SEM) and Fourier transformed infrared (FTIR) analysis. The dielectric properties of BiFeO3/Ni0.1Fe2.9O4 nanocomposite were studied as a function of temperature as well as frequency. Based on the frequency dependent of ac conductivity results, it indicated that the conduction occurs through tunneling and small polaron hopping. The composite sample shows excellent results for heavy metal (Cr6+) removal from wastewater as the removal efficiency was reached to 75% at PH 6 after 40 min. The adsorption of Cr (VI) on the surface of nanocomposite was occurred through Langmuir isotherm and follows pseudo-second-order kinetics. The goal and novelty of this work were to investigate the structural, morphological and dielectric as well as magnetic properties of multiferroic nanocomposite material (BiFeO3/Ni0.1Fe2.9O4) and test its efficiency for heavy metal removal.
