随着科学技术的进步，实际应用的需求不断增长，使得低维多铁性材料在化学和生物传感器、纳米电子、高密度数据存储设备等领域更具吸引力。通过基于溶胶-凝胶的静电纺丝工艺成功合成了一维 BiFeO3 纳米管。扫描电子显微镜和透射电子显微镜图像共同表明，在 500 °C 退火温度下观察到具有细长结构和几乎均匀直径（约 100 nm）的 BiFeO3 纳米管。通过与在 800 °C 退火温度下观察到的 BiFeO3 块体进行比较，成功地在 BiFeO3 纳米管中实现了室温增强的室温铁磁性。电子自旋共振测量结果进一步证实了在不同温度下BiFeO3纳米管中检测到了铁磁共振。 X射线光电子能谱研究证明BiFeO3纳米管中存在大量氧空位，这将在增强铁磁性方面发挥关键作用。该成果将有助于将BiFeO3的应用扩展到自旋电子器件和高密度数据存储介质的新领域。
With the progress of science and technology, the growing demands for practical applications make low-dimensional multiferroics more appealing in areas such as chemical and bio-sensors, nanoelectronic, high-density data storage devices. One-dimensional BiFeO3nanotubes were successfully synthesized by sol–gel-based electrospinning process. The images of scanning electron microscopy and transmission electron microscopy collectively demonstrate that BiFeO3nanotubes with long slender structure and virtually uniform diameter of approximately 100 nm were observed at 500 °C annealing temperature. By compared with BiFeO3bulks observed at 800 °C annealing temperature, enhanced room temperature ferromagnetism was successfully realized in BiFeO3nanotubes at room temperature. The results of electron spin resonance measurement further confirm that ferromagnetic resonances were detected in BiFeO3nanotubes at different temperature. X-ray photoelectron spectroscopy study proves the existence of plentiful oxygen vacancies in BiFeO3nanotubes, which will play a key role in terms of enhanced ferromagnetism. The results will contribute to expand the applications of BiFeO3into the new field of spintronic devices and high-density data storage media.
