Emergent Chaos-Like Dynamics of Spin-Orbit Torque-Driven Magnetic Transitions
Lisa-Marie Kern, Kai Litzius, Victor Deinhart +12
Spin-orbit torques (SOTs) are widely used to control magnetization in nanoscale electric systems and are typically assumed to drive skyrmion nucleation and motion in a deterministi…
Linear dichroic soft X-ray microscopy of ferroelectric stripe domains in epitaxial KNaNbO
M. Schneider, T. A. Butcher, S. Wagner +19
Functional properties of ferroelectric thin films are governed by domains that can be engineered by epitaxial strain. Soft X-ray microscopy can image domain structures with element…
Soft-X-ray momentum microscopy of nonlinear magnon interactions below 100-nm wavelength
Steffen Wittrock, Christopher Klose, Salvatore Perna +10
Magnons are quantised collective excitations of long-range ordered spins. At nanometre wavelengths, exchange interactions increasingly govern their dynamics, giving rise to a large…
Picosecond localization dynamics following ultrafast nanoscale magnetic switching
Daniel Metternich, Michael Schneider, Giuseppe Mercurio +28
Ultrashort laser pulses provide the fastest known way to switch magnetic order. Such excitation commonly creates nanometer-scale domains, even after homogeneous illumination when t…
Local nanoscale probing of electron spins using NV centers in diamond
Sergei Trofimov, Christos Thessalonikios, Victor Deinhart +5
Substitutional nitrogen atoms in a diamond crystal (P1 centers) are, on one hand, a resource for creation of nitrogen-vacancy (NV) centers, that have been widely employed as nanosc…
Double helical plasmonic antennas
Aleksei Tsarapkin, Luka Zurak, Krzysztof MaÄkosz +5
Plasmonic double helical antennas are a means to funnel circularly polarized light down to the nanoscale. Here, an existing design tool for single helices is extended to the case o…
