摘要
The Bi0.9Ba0.1Fe0.85Mn0.15O3 ceramic sample was prepared by sol-gel process. XRD analysis showed that it was the single-phase rhombohedral. perovskite structure. A weak ferromagnetic and ferroelectric were obtain from the hysteresis loops. The dielectric constant which increased with an increase in the magnetic field showed that the Ba-Mn codoped BFO has greater magnetocapacitance effects.
