项目摘要
In the present research, we have tried to extend our nanoscale transport measurement technique to spin transport. First, we developed a method to make a magnetic probe by coating CoFe on cabon nanotube (CNT) tips. Using these magnetic probes in our four-tip scanning tunneling microscope, we succeeded in detecting some spin signal, which is likely originated from the current-induced spin-polarization phenomenon in surface states of ultrathin bismuth films.
在目前的研究中,我们试图将我们的纳米输运测量技术扩展到自旋输运。首先,我们开发了一种通过在碳纳米管(CNT)尖端上涂覆CoFe来制造磁探针的方法。在我们的四探针扫描隧道显微镜中,我们成功地探测到了一些自旋信号,这可能是来自电流诱导的自旋极化现象的表面态的铋膜。
