Photonics of Topological Magnetic Textures

Advanced Optical Materials, EarlyView.
Localized noncollinear magetic textures imprint their geometry and topology onto traversing photonic fields endowing them with orbital angular‐momentum, chirality, and magnetoelectric densities. Abstract Topological textures in magnetically ordered materials are an important case studies for fundamental research with promising applications in data ...

Review of Rotational Symmetry Breaking in Baby Skyrme Models

, 2009
We discuss one of the most interesting phenomena exhibited by baby skyrmions -- breaking of rotational symmetry. The topics we will deal with here include the appearance of rotational symmetry breaking in the static solutions of baby Skyrme models, both ...

Large Anomalous Hall Effect, Non‐Vanishing Berry Curvature in (110) FeRh Antiferromagnet Films via Interface Strain

Advanced Science, EarlyView.
This study demonstrates a strain‐tunable anomalous Hall response in the (110)‐oriented FeRh thin film. First‐principles calculations reveal that strain‐induced symmetry lowering redistributes Berry curvature near the Fermi level via band shifts and avoided crossings.

Stray field signatures of N\'eel textured skyrmions in Ir/Fe/Co/Pt multilayer films

, 2018
Skyrmions are nanoscale spin configurations with topological properties that hold great promise for spintronic devices. Here, we establish their N\'eel texture, helicity, and size in Ir/Fe/Co/Pt multilayer films by constructing a multipole expansion to ...

Spintronic Bayesian Hardware Driven by Stochastic Magnetic Domain Wall Dynamics

Advanced Science, EarlyView.
Magnetic Probabilistic Computing (MPC) utilizes intrinsic stochastic dynamics in domain walls to establish a hardware foundation for uncertainty‐aware artificial intelligence. Thermally driven domain‐wall fluctuations, voltage‐controlled magnetic anisotropy, and TMR readout enable fully electrical, tunable probabilistic inference.

Current‐Driven Nonreciprocal Response of Nonequilibrium Skyrmions

Advanced Science, EarlyView.
A skyrmion holds great promise for spintronic applications owing to its intrinsic topological stability and high mobility under ultra‐low current excitation. Here, by means of in situ electron microscopy, we demonstrate a skyrmion diode effect and the associated current‐driven nonreciprocal skyrmion dynamics in a designed FeGe‐based microdevice.
