Abstract
- The structural, electric, and magnetic properties were investigated in multisusceptible BaAlxFe12−xO19 (x = 0, 1, 2, and 3) ceramics. It is found that the magnetic domain structure changes abruptly with the increase in the Al3+ concentration, which is responsible for the abnormal coercivity enhancement and the distinct initial magnetization behavior. Smaller Al3+ doping increases the off-center displacement of Fe3+ ions at the trigonal bipyramid by introducing compressive strain, which thus enhances the stability of the ferroelectric phase and improves the ferroelectric Curie temperature of BaFe12O19. Moreover, more stable Al3+ ions can increase the resistance of BaFe12O19. The present results highlight the possible application of Al3+ doped BaFe12O19 ceramics as a multisusceptible single-phase material on multifunctional electronic devices. [ABSTRACT FROM AUTHOR]
