Magnetic domain walls in constrained geometries
P. -O. Jubert, R. Allenspach, A. Bischof
Magnetic domain walls have been studied in micrometer-sized Fe20Ni80 elements containing geometrical constrictions by spin-polarized scanning electron microscopy and numerical simu…
Snell's law for surface electrons: Refraction of an electron gas imaged in real space
Jascha Repp, Gerhard Meyer, Karl-Heinz Rieder
On NaCl(100)/Cu(111) an interface state band is observed that descends from the surface-state band of the clean copper surface. This band exhibits a Moire-pattern-induced one-dimen…
Nanometers-thick self-organized Fe stripes: bridging the gap between surfaces and magnetic materials
Olivier Fruchart, Mustafa Eleoui, Jan Vogel +3
We have fabricated 5nm-high Fe(110) stripes by self-organized (SO) growth on a slightly vicinal R(110)/Al2O3(11-20) surface, with R=Mo, W. Remanence, coercivity and domain patterns…
Site determination and thermally assisted tunneling in homogenous nucleation
Jascha Repp, Gerhard Meyer, Karl-Heinz Rieder +1
A combined low-temperature scanning tunneling microscopy and density functional theory study on the binding and diffusion of copper monomers, dimers, and trimers adsorbed on Cu(111…
