Curvilinear magnonic crystal based on 3D hierarchical nanotemplates

Gianluca Gubbiotti, Olha Bezsmertna, Oleksandr V. Pylypovskyi +11

Curvilinear magnetic nanostructures enable control of magnetization dynamics through geometry-induced anisotropy and chiral interactions as well as magnetic field modulation. In th…

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…

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…
