论文摘要
散装BifeO3中磁截图的存在仍然是一个调查问题，也是研究Nano Bifeo3中磁截图效应的问题。目前的工作证明了在室温下在超帕磁性BifeO3纳米颗粒中存在磁静脉应变，并以P（VDFTRFE）为复合形式的磁电耦合性能。尽管很少有关于间接方法证明的大量BifeO3中磁截图效应的报道，但在这项工作中采用了直接方法（应变计）来检查超帕磁性bifeo3的磁梗。此外，通过锁定技术进行了优化的BifeO3_P（VDF-TRFE）纳米复合膜的锁定技术观察到高磁电耦合系数。这些纳米复合膜还表现出室温多性特性。这些结果为材料提供了材料的各个方面，具有巨大的潜力，用于旋转型和磁电机应用中的实际应用。我们报告了使用SuperParamagnetic BifeO3_P（VDF-TRFE）纳米复合膜检测AC磁场的磁电传感器。
The existence of magnetostriction in bulk BiFeO3 is still a matter of investigation and it is also an issue to investigate the magnetostriction effect in nano BiFeO3. Present work demonstrates the existence of magnetostrictive strain in superparamagnetic BiFeO3 nanoparticles at room temperature and the magnetoelectric coupling properties in composite form with P(VDFTrFE). Despite few reports on the magnetostriction effect in bulk BiFeO3 evidenced by the indirect method, the direct method (strain gauge) was employed in this work to examine the magnetostriction of superparamagnetic BiFeO3. In addition, a high magnetoelectric coupling coefficient was observed by the lock-in technique for optimized BiFeO3_P(VDF-TrFE) nanocomposite film. These nanocomposite films also exhibit room-temperature multiferroic properties. These results provide aspects of material with immense potential for practical applications in spintronics and magneto-electronics applications. We report a magnetoelectric sensor using superparamagnetic BiFeO3_P(VDF-TrFE) nanocomposite film for detection of ac magnetic field.
