Emergent Chaos‐Like Dynamics of Spin–Orbit‐Torque‐Driven Magnetic Transitions

Small, EarlyView.
By combining anisotropy‐engineered nanometer‐scale nucleation sites with time‐resolved x‐ray holography and micromagnetic modeling, magnetization dynamics are directly imaged, revealing chaos‐like fluctuations and skyrmion shedding and highlighting the intrinsic complexity of spin‐orbit torque driven systems.

Fluid‐Induced Magnetic Enhancement in Sandstone Friction Experiments: Implications for Coseismic Fault Temperature Estimates

Geophysical Research Letters, Volume 53, Issue 11, 16 June 2026.
Abstract Constraining peak temperature during seismic slip is essential for quantifying earthquake energy budgets and fault weakening. Rock magnetic methods provide a sensitive means of estimating shear‐induced coseismic temperature rise; however, the role of fluids in friction‐induced magnetic alterations remains poorly constrained.

2D Magnetic and Topological Quantum Materials and Devices for Ultralow Power Spintronics

Advanced Functional Materials, Volume 36, Issue 44, 1 June 2026.
2D magnets and topological quantum materials enable ultralow‐power spintronics by combining robust magnetic order with symmetry‐protected, Berry‐curvature‐driven transport. Fundamentals of 2D anisotropy and spin‐orbit‐coupling induced band inversion are linked to scalable growth and vdW stacking.

Current‐Driven Nonreciprocal Response of Nonequilibrium Skyrmions

Advanced Science, Volume 13, Issue 31, 4 June 2026.
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.

Nonlinear Strain‐Mediated Magnetoelectric Coupling in Sub‐Microscale Ni/BPZT Thin‐Film Devices

Advanced Electronic Materials, Volume 12, Issue 11, 8 June 2026.
Sub‐micrometer Ni/BPZT thin‐film magnetoelectric devices with lateral gates enable localized, low‐voltage strain control of magnetization. By combining anisotropic magnetoresistance, nitrogen‐vacancy magnetometry, multiphysics strain simulations, and micromagnetic modelling, the study quantitatively links ferroelectric strain hysteresis to magnetic ...

Imaging and Linking Spatial Magnetic Nanoparticle Distribution to Microbead Torques Using Soft X‐Ray Laminography

Advanced Physics Research, Volume 5, Issue 6, June 2026.
Nanoscale 3D imaging of superparamagnetic microbeads via soft X‐ray laminography reveals the structural origin of the observed torques in cell movement experiments. These microbeads are found to have an uneven distribution of magnetic magnetite nanoparticles.
