Effects of Bismuth Donor Doping on the Phase Structure and the Magnetic and Ferroelectric Properties of Fe-doped BaTiO3

다국어 초록 (Multilingual Abstract)

To compensate for the acceptor dopant Fe3+ in Fe-doped BaTiO3 ceramics, we introduced a donordopant into these ceramics in order to investigate its effects on their phase structure and on themagnetic and ferroelectric properties. We prepared 5% Fe-doped BaTiO3 ceramic and used Bi3+as the donor dopant. We found that the formation of the hexagonal phase in Fe-doped BaTiO3 wassuppressed and that the magnetic and the ferroelectric properties of these ceramics were changed bythe Bi3+ doping. These results indicate that the structural, magnetic and ferroelectric properties ofBaTi0.95Fe0.05O3 ceramics can be controlled by Bi3+ doping and that a multiferroic property wasobserved in the Ba0.98Bi0.02Ti0.95Fe0.05O3 ceramic.
