dc.description.abstract | An enhanced low-frequency dielectric constant, ( ε′ ∼ 104), and ferromagnetic behavior at room temperature were observed in Bi Y Fe Ni O 0.99 0.01 0.99 0.01 3 (BYFNO) ceramic sintered by a modified solid state reaction method. The anti-ferromagnetic (AFM) nature of BiFeO3 (BFO) changed to ferromagnetic (FM) with saturation magnetization, Ms, and coercivity Hc values of ∼0.03 / . . μ f u B and ∼250 Oe, respectively at room temperature. The XRD patterns revealed that the co-doping of + Y3 and + Ni 2 ions at the A− and B− sites of BiFeO3 (BFO) resulted in a rhombohedrally distorted perovskite structure. This result was discussed in terms of the modification of the cycloidal spin structure, presence of + Ni 2 carriers and preservation of oxygen vacancy during the sintering process. This enhanced properties entitle the Bi Y Fe Ni O 0.99 0.01 0.99 0.01 3 one of the few multiferroic materials that exhibits both significant ferromagnetic and dielectric behaviors at room temperature. | |
