论文摘要
为了阐明SRNBO3（SNO）超薄膜的自旋松弛机制，在金属绝缘子过渡的两侧测量了一系列具有各种厚度的SNO膜的传输特性。旋转轨道散射时间是从弱抗钙化理论的磁阻的分析中得出的，发现旋转轨道散射时间与动量散射时间成反比。该结果是用d'yakonov perel“机制来解释的，这表明了占主导地位的rashba效应。 RASHBA参数的值在报告的其他超薄薄膜报告的值中最大。
To elucidate the spin relaxation mechanism of SrNbO3 (SNO) ultrathin films, the transport properties of a series of SNO films with various thicknesses were measured on both sides of the metal insulator transition. The spin orbit scattering time was deduced from the analysis of the magnetoresistance with weak antilocalization theory, and it was found that the spin orbit scattering time was inversely proportional to the momentum scattering time. This result was explained in terms of the D`Yakonov Perel` mechanism, indicative of the dominant Rashba effect. The values of the Rashba parameter were largest in the values reported for other ultrathin films of metallic oxides.
