Magnetoelectric effects in Co-Ti Co-doped M-Type Barium Hexaferrites

  • 摘要: 磁电多铁性材料兼具电极化及磁性,可用于构建新型传感器和高密度存储器件.但对于单相多铁性材料,大多工作温度低且所需磁场强度较高,无法满足实用化需求.近来发现六角铁氧体可明显提高这两方面特性,但还需提高其工作温度及电阻率.我们采用Co-Ti元素对M-型钡六角铁氧体进行大剂量共掺杂,制备一系列的铁氧体陶瓷BaFe12-2xCoxTixO19 (x=0~4).同时利用物理性能综合测试仪(PPMS)及其他检测仪器搭建了一套磁电测试系统,并结合LabVIEW软件进行编程,对样品的磁性、电性、磁介电和磁电耦合特性进行系统表征.结果表明,Co-Ti共掺杂可显著改变M型钡六角铁氧体的矫顽场及饱和磁化强度.同时,这种掺杂可使漏电流降低到3个量级(掺杂量x=2).值得一提的是,我们在掺杂量为x=2的样品中观测到室温下的磁介电效应,同时在100K以下观测到明显的磁致铁电极化,且其电极化方向可以被磁场反转.该结果在探索新型多铁六角铁氧体及推进其应用化进程具有一定的意义.
    Abstract: Magnetoelectric multiferroic materials possess both magnetic and ferroelectric properties couple, which have attracted intensive investigations from both fundamental and application potentials such as new concept sensors or high density storage devices. However, update to now most of the single phase multiferroics can only work at low temperatures and large operation magnetic fields. In recent years, people found that hexaferrites with conical spiral spin structure can both improved the working temperature and reduced operation magnetic field. In this work, we applied high level Co-Ti codopping into M-type hexaferrites to form BaFe12-2xCoxTixO19 (x=0~4) ceramics by solid state reaction. Their magnetic, electrical, magnetodielectric and magnetoelectric properties have been investigated by a combination of Physical Properties Measurement System (PPMS) and other testing instruments, which are controlled by a LabVIEW program. It was revealed that Co-Ti codoping can significantly change the magnetization and coercivity of the BaFe12-2xCoxTixO19. Meanwhile, Co-Ti doping can also greatly suppress the leakage current by about three orders (x2). Notably, we observed apparent magnetic field induced ferroelectricity polarization in some compositions, at temperatures below 100K. Finally, magnetodielectric effect (up to 0.9%) at room temperature were obtained in the co-doped sample (x=2). The present results could provide a new route for exploring new type of multiferroic hexaferrites and their potential applications.
