摘要:

利用非弹性隧道谱(IETS)、X射线磁性圆二色性(XMCD)和密度泛函理论(DFT)研究了双层镍茂分子(Nc)吸附在Cu(100)表面的自旋翻转激发.结果表明,该分子不仅在Cu(100)上保持其磁矩和磁各向异性,而且在包括针尖在内的不同金属环境中也保持其磁性。利用这种分子的有效自旋翻转激发,我们展示了这样的分子功能化尖端如何通过双自旋激发过程将表面支持的Nc的非弹性信号提高几乎一个数量级。

英文摘要:

We studied the spin-flip excitations of a double-decker nickelocene molecule (Nc) adsorbed on Cu(100) by means of inelastic tunneling spectroscopy (IETS), X-ray magnetic circular dichroism (XMCD) and density functional theory calculations (DFT). The results show that the molecule preserves its magnetic moment and magnetic anisotropy not only on Cu(100), but also in different metallic environments including the tip apex. Taking advantage of the efficient spin-flip excitation of this molecule, we show how such a molecular functionalized tip boosts the inelastic signal of a surface supported Nc by almost one order of magnitude thanks to a double spin-excitation process.
