In this work, we reported the fabrication and magnetoelectric coupling properties of the multiferroic CoFe₂O₄‐PbZr_0.2Ti_0.8O₃ (CFO‐PZT) coaxial nanofibers synthesized by electrospinning technique. The coaxial structure of nanofibers was demonstrated by magnetic force microscope and transmission electron microscope. The multiferroic properties of coaxial nanofibers have been revealed by magnetic hysteresis loops and piezoresponse amplitude butterfly curves and phase hysteresis loops. The as‐prepared coaxial nanofibers show an effective piezoelectric coefficient d₃₃ of 30 pm/V and a saturated magnetization of 12 emu/g. Their magnetoelectric response has been probed by means of the localized changes in magnetization after poling the domains of the composite system. A static, large converse magnetoelectric coupling coefficient of 1.2 × 10⁻⁸ s/m was obtained in a single CFO‐PZT nanofiber.

CoFe2O4-Pb（Zr0.2Ti0.8）O3同轴纳米纤维中的磁电耦合

在这项工作中，我们报告了通过电纺丝技术合成的多铁性CoFe ₂ O ₄ -PbZr _0.2 Ti _0.8 O ₃（CFO-PZT）同轴纳米纤维的制备和磁电耦合特性。通过磁力显微镜和透射电子显微镜证明了纳米纤维的同轴结构。同轴纳米纤维的多铁性已通过磁滞回线，压电响应振幅蝶形曲线和相滞回线得以揭示。制备的同轴纳米纤维显示出有效的压电系数d ₃₃30 pm / V的饱和磁化强度和12 emu / g的饱和磁化强度。通过极化复合系统的磁畴后，通过磁化的局部变化来探究其磁电响应。在单个CFO-PZT纳米纤维中获得了1.2×10 ^-8 s / m的静态大反向磁电耦合系数。
