Abstract
Bi0.9−x Ba0.1K x FeO3 (x = 0, 0.01, 0.02) nanoparticles have been successfully prepared using sol–gel method. X-ray diffraction data revealed rhombohedral distorted perovskite structure for all samples. The magnetization and the leakage current density both increased with K doping. Space charge limited conduction was found to be the dominant mechanism in whole electric field for all the samples investigated by plotting log J versus log E. In addition, the band gaps of all nanoparticles were investigated and the values showed no obvious change with the increase of K content due to the interplay of oxygen vacancies and bond angle of Fe–O–Fe. The dielectric properties including the dielectric constant and loss were also investigated.
