Abstract
The structural, magnetic and ferroelectric properties of polycrystalline A-site (A = Ho, Pr and Ce of 10%) doped BiFeO3, which were prepared by the solid-state and rapid sintering methods, have been investigated. The powder X-ray diffraction pattern reveals that all the samples show rhombohedral perovskite structure R3c. The Ho-doped BiFeO3 shows that the magnetic property is slightly increased due to compressive lattice distortion and Ho3+ ion doping effect. For the Pr and Ce doped BiFeO3, the remnant polarization and coercive field increased because Pr3+ and Ce3+ ions substitution suppressed oxygen vacancies.
