Scattering three closed strings off a Dp-brane in pure spinor formalism
Andreas Bischof, Michael Haack, Stephan Stieberger
We compute the disk amplitude of three closed strings in the pure spinor formalism. Among others, this amplitude probes tree-level gravitational interactions in the presence of Dp-…
Closed string disk amplitudes in the pure spinor formalism
Andreas Bischof, Michael Haack
We evaluate closed string disk amplitudes in the pure spinor formalism. We focus on low point functions (two- and one-point functions) but our analysis is also relevant for higher…
Domain Wall Motion and Interfacial Dzyaloshinskii-Moriya Interactions in Pt/Co/Ir/Ta Multilayers
Kowsar Shahbazi, Joo-Von Kim, Hans T. Nembach +6
The interfacial Dzyaloshinskii-Moriya interaction (DMI) is important for chiral domain walls (DWs) and for stabilizing magnetic skyrmions. We study the effects of introducing incre…
Achiral tilted domain walls in perpendicularly magnetized nanowires
B. Boehm, A. Bisig, A. Bischof +3
Perpendicularly magnetized nanowires exhibit distinct domain wall types depending on the geometry. Wide wires contain Bloch walls, narrow wires Néel walls. Here, the transition reg…
Direct observation of domain-wall configurations transformed by spin currents
M. Klaui, P. -O. Jubert, R. Allenspach +7
Direct observations of current-induced domain-wall propagation by spin-polarized scanning electron microscopy are reported. Current pulses move head-to-head as well as tail-to-tail…
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…
