| Abstract: | Spin-polarized scanning tunneling microscopy and spectroscopy (SP-STM/STS) has been performed on clean and sulfur-covered three-dimensional Fe islands on W(1 1 0). Upon dosing with H2S the island surface is covered with 1/3 ML S leading to a c(3 × 1) reconstruction. The characteristic magnetic vortex structure is observable before and after dosing, even though the electronic structure of the surface is modified as is shown by SP-STS. |
