Vortex core switching by coherent excitation with single in-plane magnetic field pulses
Markus Weigand, Bartel Van Waeyenberge, Arne Vansteenkiste +9
The bistability of the core magnetization of nano-scaled magnets with a magnetic vortex configuration has great potential for data storage applications. To exploit this, reliable s…
Polarisation selective magnetic vortex dynamics and core reversal in rotating magnetic fields
M. Curcic, B. Van Waeyenberge, M. Weigand +8
A magnetic vortex occurs as an equilibrium configuration in thin ferromagnetic platelets of micron and sub-micron size and is characterised by an in-plane curling magnetisation. At…
Time-Resolved X-ray Microscopy of Spin-Torque-Induced Magnetic Vortex Gyration
Markus Bolte, Guido Meier, Benjamin Krueger +10
Time-resolved X-ray microscopy is used to image the influence of alternating high-density currents on the magnetization dynamics of ferromagnetic vortices. Spin-torque induced vort…
Existence of Density Functionals for Excited States and Resonances
B. G. Giraud, K. Kato, A. Ohnishi +1
We show how every bound state of a finite system of identical fermions, whether a ground state or an excited one, defines a density functional. Degeneracies created by a symmetry g…
