论文摘要
我们在PB（111）底物上创建了有序的磁性镍分子岛。通过使用非弹性电子隧道光谱（IET）和密度功能理论，我们表征了这些岛的磁反应。这使我们能够得出结论，这些岛屿存在局部和集体磁激发。此外，我们表明镍岛岛上在超导PB（111）表面上表现出复杂的非连线自旋模式，从而打开了使用分子阵列来设计具有对拓扑超导性重要意义的工程旋转纹理的可能性。
We create ordered islands of magnetically anisotropic nickelocene molecules on a Pb (111) substrate. By using inelastic electron tunneling spectra (IETS) and density functional theory, we characterize the magnetic response of these islands. This allows us to conclude that the islands present local and collective magnetic excitations. Furthermore, we show that nickelocene islands present complex non-collinear spin patterns on the superconducting Pb (111) surface, opening the possibility of using molecular arrays to engineer spin textures with important implications on topological superconductivity.
