dc.description.abstract
The surface of expanded face-centered tetragonal antiferromagnetic Mn films of
a few atomic monolayers thickness grown epitaxially on Co/Cu(001) was
investigated at room temperature by scanning tunneling microscopy and scanning
tunneling spectroscopy using a ferromagnetic ring-shaped bulk iron probe. We
show that the main contribution to the contrast modulation observed as a
function of Mn thickness in differential conductance maps is not due to spin-
polarized tunneling from a layerwise antiferromagnetic spin alignment.
Instead, it is mainly of electronic origin resulting from layer-dependent
electronic properties of the Mn film, probably related to different levels of
intermixing with Co atoms.On the atomic scale, theMn surface demonstrates a
geometrical reconstruction with a (12 × 2) periodicity in two orthogonal
domains on the fourfold symmetric substrate with an apparent surface
corrugation of up to 0.3 A° . Simultaneously recorded differential conductance
maps show different textures in the two orthogonal domains, providing evidence
for noncollinearity in the Mn surface spin structure.
