Atomic scale spin-dependent STM on magnetite using antiferromagnetic STM tips.
STM tips made from antiferromagnetic MnNi have been used to investigate the atomic structure of the (001) and (111) surfaces of Fe3O4. The clean (001) surface displays a ( radical2 x radical2)R45 degrees superlattice, which is attributed to charge-ordering on the surface, where Fe(2+)-Fe2+ and Fe(3+)-Fe3+ dimers can be discriminated. The oxygen-terminated (111) surface is characterized by a hex...
متن کاملThe Atomic-scale Characterization of Defects on Cleaved Vanadium and Molybdenum Oxide Surfaces Using Stm
Scanning tunneling microscopy (STM) was used to determine the structure of cleaved, single crystal surfaces of V20 5, V60 13, Mo 180 52, and Mo80 23. Constant current images were recorded in ultrahigh vacuum and in air. By imaging well-defined surfaces that exhibit structural and chemical similarities, and comparing the observations to the known bulk structures, it is possible to establish a re...
متن کاملAtomically resolved spin-dependent tunneling on the oxygen-terminated Fe3O4(111).
We employ spin-polarized STM to study the spin-dependent tunneling between a magnetite (111) sample and an antiferromagnetic tip through a vacuum barrier at room temperature. Atomic scale STM images show significant magnetic contrast corresponding to variations in the local surface states induced by oxygen vacancies. The estimated variations in tunneling magnetoresistance of 250% suggest that t...
متن کاملSpin-polarized STM for a Kondo adatom.
We investigate the bias dependence of the tunneling conductance between a spin-polarized (SP) scanning tunneling microscope (STM) tip and the surface conduction states of a normal metal with a Kondo adatom. Quantum interference between tip-host metal and tip-adatom-host metal conduction paths is studied in the full range of the Fano parameter q. The spin-polarized STM gives rise to a splitting ...
متن کاملAtomic row doubling in the STM images of Cu(014)-O obtained with MnNi tips.
We report on scanning tunneling microscopy studies of the Cu(014)-O surface using MnNi tips. Remarkably, the results show a regular apparent doubling of surface atomic rows in the {110} direction. A qualitative explanation of this feature based on tight binding and density functional theory calculations of the electronic structure of the tip is presented. Double imaging of the same atom by diff...
