“…The result was responded to the SEM figure. Another factor, the magnetization in BFVO was due to occurring in super exchange interaction between Fe 2+ and Fe 3+ ions [7]. BFVO requires charged compensation with the addition of V 5+ ions, which had been achieved by the transformation of Fe 3+ to Fe 2+ or oxygen vacancies decreased.…”

“…Several groups had reported partial substitution of Fe 3+ with V 5+ ions. Priyanka Godara and Reetu Dahiya et al reported the change of magnetic and dielectric properties with the co-doped with Ba (Sr) and small amount of V. Rietveld refinement studies showed that all samples [7,8]. Benfang Yu et al reported that the electrical properties were improved with the co-doped with La and V [9].…”

BiFe 1-x V x O 3 (x = 0.00, 0.03, 0.05, 0.07, 0.09) ceramics were prepared by solid-sate reaction method. The effect of V 5+ substitution on phase structure, morphology, magnetic and dielectric properties had been investigated. The Rietveld refinement of the X-Ray diffraction data from the BiFe 1-x V x O 3 (BFVO) ceramics showed samples with rhombohedral structure (R3c) for x = 0.00-0.07. When x = 0.09, partial phase structural be translated to orthorhombic phase (Pnma). Morphology showed two kinds of crystal and proved the phase to be transition. Magnetic measurements exhibited weak ferromagnetic behavior of sample. BiFe 0.93 V 0.07 O 3 ceramic exhibited the highest value of saturation magnetization. Due to V 5+ substitution, maybe BFVO attributed weak ferromagnetism to structure distortion and phase transition. Dielectric constant kept a stable value in a wide range frequency of 1 MHz to 1 GHz. With V 5+ ions increasing, dielectric constant increased significantly, while dielectric loss kept a low value. These results indicated that BFVO may be promising for application in magneto-electric devices.

“…The previous studies showed that RE substitution for Bi-sites created weak ferromagnetic order. That was attributed to partial destruction of spiral spin structure due to structural destruction and RE 3+ -RE 3+ and/or RE 3+ -Fe 3+ super-exchange interactions [14][15][16]. The polarization-electric field hysteresis (P-E) loops of BFO and BYFNO samples measured at room temperature are shown in Fig.…”

In this study, multiferroicMultiferroic Bi1-xYxFe0.975Ni0.025O3 (x = 0.00, 0.05, 0.10, and 0.15) called as (Y, Ni) co-doped BiFeO3 materials were synthesized by a sol-gel method. and characterized by X-ray diffraction diagrams and(XRD), energy-dispersive X-ray (EDX) and vibrating sample magnetization (VSM) measurements demonstrated. The result showed that Bi1-xYxFe0.975Ni0.025O3all investigated materials waspresent a single phase of the perovskite-type rhombohedral structure. Ferromagnetism and ferroelectricity of the Bi1-xYxFe0.975Ni0.025O3 materials have been investigated. Results showed that the co-doping by (Y, Ni) for (Bi, Fe) have affected in enhancing by the (Y, Ni) co-doping, as a result the ferroelectric polarization and magnetization of BiFeO3. The magnetic characterization indicated that the ferromagnetic behavior wasthe initial BiFeO3 materialwere enhanced with increasing concentration of Y3+ for (Y, Ni) co-substituted of BiFeO3. Which could beion. It is attributed to the defferentdifference of the magnetic momentmoments of Ni2+ and Fe3+, and+ ions, as well as the Y3+-Fe3+,+ and Y3+-Ni2+ super-exchange interaction. Theinteractions. The characteristics of the investigated materials, such as remanent magnetization (Mr), saturation magnetization (Ms), remanent polarization (2Pr) and saturation polarization (2Ps) continuously increase upon increasing in the range of x from 0.00 to 0.15. When x = 0.15, the values of Mr and Ms are 0.078 and 0.794 emu/g, respectively. The values of 2Pr and 2Ps are 16.58 and 27.99 µC/cm2, respectively. Origin of ferromagnetic and ferroelectric properties of Bi1-xYxFe0.975Ni0.025O3 materials will be discussed in this paper.
