Enhanced magnetic and dielectric behavior in Co doped BiFeO3 nanoparticles
چکیده انگلیسی
Magnetic and dielectric properties of Co doped BiFeO3 (BFO) nanoparticles (13 nm) have been investigated. The dopant Co2+ converts spherical morphology to cubic nanostructures. The significant changes in temperature dependence of magnetization may be due to magnetic disorder phase induced by divalent Co. The substitution of Fe by Co disrupts cycloidal spin structure of BFO and improves the ferromagnetic property. Enhancement of the saturation magnetization and coercivity by about 10 times in doped BFO are due to changes in morphology. High dielectric constant of about 670 and low loss at room temperature show Co doped BFO as promising material for multifunctional devices.
