dc.description.abstractControl and manipulation of emergent magnetic orders in strongly correlated electron materials promises new opportunities for device concepts which exploit these for spintronics applications. For their technological exploitation it is important to understand the role of surfaces and interfaces to other materials, and their impact on the emergent magnetic orders. Here, we demonstrate for iron telluride, the non-superconducting parent compound of the iron chalcogenide superconductors, determination and manipulation of the surface magnetic structure by low temperature spin-polarized scanning tunneling microscopy. Iron telluride exhibits a complex structural and magnetic phase diagram as a function of interstitial iron concentration. Several theories have been put forward to explain the different magnetic orders observed in the phase diagram, which ascribe a dominant role either to interactions mediated by itinerant electrons or to local moment interactions. Through the controlled removal of surface excess iron, we can separate the influence of the excess iron from that of the change in the lattice structure.
