چکیده انگلیسی
A multiferroic 0.8BiFeO3 ââ¯0.2BaTiO3 (0.8BF-BaT) ceramic was prepared by solid-state reaction to study the magnetic control of its ferroelectric polarization and ferromagnetic properties. The influence of the magnetic field H on the ferroelectric polarization of 0.8BF-BaT ceramic was investigated. The maximum displacement current density Jm and the remanent polarization Pr of 0.8BF-BaT increased by 35% and 20% respectively after it being magnetized, indicating that the polarization was suppressed in the magnetic domain walls. Under a magnetic field of Hâ¯=â¯0.7â¯T, Jm and Pr decreased by 6.1% and 6.4% respectively, revealing coupling between polarization P and magnetic field H. The magnetic properties of BiFeO3 were improved by introducing of BaTiO3 and the magnetic Néel temperature TN increased by 70â¯K because of structural effects.
