Inferring Magnetic Material Parameters from Statistical Measures in Strongly Fluctuating Magnetization Dynamics

Kübra Kalkan, Atreya Majumdar, Ross Knapman +5

Magnetic material parameters such as the exchange stiffness and magnetic anisotropy govern the behavior and functionality of magnetic systems, yet their local inference from magnet…

Defect Detection in Magnetic Systems Using U-Net and Statistical Measures

Ross Knapman, Atreya Majumdar, Nasim Bazazzadeh +4

Local material inhomogeneities can strongly influence magnetization dynamics and macroscopic magnetic properties, yet detecting such defects from magnetic imaging data remains chal…

3D Magnetic Textures with Mixed Topology: Unlocking the Tunable Hopf Index

Maria Azhar, Sandra C. Shaju, Ross Knapman +2

Knots and links play a crucial role in understanding topology and discreteness in nature. In magnetic systems, twisted, knotted and braided vortex tubes manifest as Skyrmions, Hopf…

Numerical Calculation of the Hopf Index for 3D Magnetic Textures

Ross Knapman, Maria Azhar, Alessandro Pignedoli +4

To gain deeper insight into the complex, stable, and robust configurations of magnetic textures, topological characterisation has proven essential. In particular, while the skyrmio…

Spacetime magnetic hopfions: from internal excitations and braiding of skyrmions

R. Knapman, T. Tausendpfund, S. A. Díaz +1

Spatial topology endows topological solitons, such as skyrmions and hopfions, with fascinating dynamics. However, the temporal dimension has so far provided a passive stage on whic…

Current-induced H-shaped-skyrmion creation and their dynamics in the helical phase

Ross Knapman, Davi R. Rodrigues, Jan Masell +1

Inevitable for the basic principles of skyrmion racetrack-like applications is not only their confined motion along one-dimensional channels but also their controlled creation and…

Nonlinear dynamics of topological ferromagnetic textures for frequency multiplication

Davi R. Rodrigues, Jonas Nothhelfer, Morteza Mohseni +3

We propose that the non-linear radio-frequency dynamics and nanoscale size of topological magnetic structures associated to their well-defined internal modes advocate for their use…
