On local CR-transformations of Levi-degenerate group orbits in compact Hermitian symmetric spaces
Wilhelm Kaup, Dmitri Zaitsev
Let be a real-analytic hypersurface in or, more generally, a CR-submanifold in a complex manifold of arbitrary CR-codimension. This paper addresses the question, when…
Self-assembly of iron nanoclusters on the Fe3O4(111) superstructured surface
N. Berdunov, G. Mariotto, S. Murphy +1
We report on the self-organized growth of a regular array of Fe nanoclusters on a nanopatterned magnetite surface. Under oxidizing preparation conditions the (111) surface of magne…
Room temperature study of a strain-induced electronic superstructure on a magnetite (111) surface
N. Berdunov, S. Murphy, G. Mariotto +1
A magnetite (Fe3O4) single crystal (111) surface has been studied at various oxygen-iron surface stoichiometries. The stoichiometry was modified by controlling the in-situ sample a…
Atomically Resolved Spin-Dependent Tunnelling on the Oxygen-Terminated Fe3O4 (111)
N. Berdunov, S. Murphy, G. Mariotto +1
We employ spin-polarized (SP) STM to study the spin-dependent tunneling between a magnetite (111) sample and an antiferromagnetic tip through a vacuum barrier at room temperature.…
