标题： Making Closed-Shell Lead-Pthalocyanine Paramagnetic on Pb(100)

摘要： 铅酞菁（PbPc），一种非平面分子，在Pb(100)上使用扫描隧道谱学进行研究。 发现当中心Pb离子指向（PbPc$\downarrow$）或远离（PbPc$\uparrow$）基底时，分子轨道发生刚性位移，并从分子与其镜像电荷之间的相互作用中得到理解。 在超导能隙内部，观察到岛上的PbPc$\uparrow$分子出现Yu-Shiba-Rusinov（YSR）共振，表明存在磁矩。 这种束缚态既不存在于PbPc$\downarrow$分子上，也不存在于沉积过程中失去Pb离子的孤立PbPc$\uparrow$或分子（H$_0$Pc）中。 YSR能量取决于分子邻居的方向和类型。 我们分析了PbPc的垂直偶极矩的作用。 显示英文摘要

摘要： Lead phthalocyanine (PbPc), a non-planar molecule, is studied on Pb(100) using scanning tunneling spectroscopy. A rigid shift of the molecular orbitals is found between molecules with the central Pb ion pointing to (PbPc$\downarrow$) or away (PbPc$\uparrow$) from the substrate and understood from the interaction between the molecules and their image charges. Inside the superconducting energy gap, Yu-Shiba-Rusinov (YSR) resonances are observed for PbPc$\uparrow$ molecules in islands indicating the presence of a magnetic moment. Such bound states are neither present on PbPc$\downarrow$ molecules nor isolated PbPc$\uparrow$ or molecules that lost the Pb ion during deposition (H$_0$Pc). The YSR energies vary depending on the orientation and type of the molecular neighbors. We analyze the role of the out-of-plane dipole moment of PbPc.
