采用溶胶-凝胶法合成了Mg掺杂的BiFeO 3（BFO）多铁性纳米粒子，并对其磁性和铁电性能进行了研究。由于Mg 2+离子取代，磁化强度显著增加，并且高于报道的具有类似掺杂水平的其他A位取代的BFO。这种强磁化强度的提高源于锁在摆线内的潜在磁化强度的释放，这是由钙钛矿结构容差因子边缘处的小半径Mg 2+离子的取代引起的。与原始的BFO相比，掺杂的Bi0.98Mg0.02FeO3在室温下表现出五倍的改善的磁化强度，同时改善了铁电性能。磁性和铁电性能的提高表明掺杂BFO在数据存储和磁电器件方面具有巨大的潜力。
Mg-substituted BiFeO3(BFO) multiferroic nanoparticles were synthesized by a facile sol-gel route and their magnetic and ferroelectric properties were investigated. Due to Mg2+ion substitution, the magnetization is dramatically increased and higher than the other A-site substituted BFO reported with similar doping level. Such strong magnetization improvement originates from the release of latent magnetization locked within the cycloid, which is caused by the substitution of small-radius Mg2+ion at the edge of the perovskite-structure tolerance factor. Compared to the pristine BFO, the as-doped Bi0.98Mg0.02FeO3exhibits five-fold improved magnetization with simultaneously improved ferroelectric properties at room temperature. Increased magnetic and ferroelectric properties suggest the doped BFO possesses great potential for data storage and magnetoelectric devices.
