Curvature induced modifications of chirality and magnetic configuration in perpendicular magnetized films
David Raftrey, Dhritiman Bhattacharya, Colin Langton +8
Designing curvature in three-dimensional (3D) magnetic nanostructures enables controlled manipulation of local energy landscapes, allowing for the modification of noncollinear spin…
Nematicity of a Magnetic Helix
Z. Tumbleson, S. A. Morley, E. Hollingworth +18
A system that possesses translational symmetry but breaks orientational symmetry is known as a nematic phase. While there are many examples of nematic phases in a wide range of con…
Quantifying the Topology of Magnetic Skyrmions in three Dimensions
David Raftrey, Simone Finizio, Rajesh V. Chopdekar +7
Magnetic skyrmions have so far been treated as two-dimensional spin structures characterized by a topological winding number describing the rotation of spins across the skyrmion. H…
Controlled Ordering of Room-Temperature Magnetic Skyrmions in a Polar Van der Waals Magnet
Peter Meisenheimer, Hongrui Zhang, David Raftrey +10
Control and understanding of ensembles of skyrmions is important for realization of future technologies. In particular, the order-disorder transition associated with the 2D lattice…
Field-driven dynamics of magnetic Hopfions
D. Raftrey, P. Fischer
We present micromagnetic simulations on resonant spin wave modes of magnetic Hopfions up to 15 GHz driven by external magnetic fields. A sharp transition is found around 32 mT coin…
