Switchable Magnonic Crystals Based on Spin Crossover/CrSBr Heterostructures

Advanced Materials, Volume 38, Issue 51, 11 September 2026.
Multiscale modeling is employed to investigate the functionality of a light‐controlled, tunable magnonic crystal based on spin‐crossover Fe‐pz molecules integrated with a monolayer of CrSBr. Ab initio simulations confirm that the molecules remain functional on the CrSBr surface, while a semiclassical elastic model demonstrates that light‐induced ...

Observation of the dominant spin-triplet supercurrent in Josephson spin valves with strong Ni ferromagnets

Physical Review Research, 2020
We study experimentally nanoscale Josephson junctions and Josephson spin valves containing strongly ferromagnetic Ni interlayers. We observe that in contrast to junctions, spin valves with the same geometry exhibit anomalous I_{c}(H) patterns with two ...

Inverse Design of Two‐Dimensional Magnonic Crystals via Topology Optimization with Frequency‐Domain Micromagnetics

Small Structures
Magnonic crystals (MCs) offer magnetic platforms for manipulating propagation characteristics of magnons, the quanta of spin waves. Due to the complex relationship between lattice geometry and magnonic band dispersion, establishing general design ...

Stochastic Dynamics of Domain Wall on a Racetrack: Impact of Line‐Edge Roughness

physica status solidi (RRL) – Rapid Research Letters, Volume 20, Issue 9, September 2026.
Line‐edge roughness is shown to induce stochastic domain‐wall pinning in ferromagnetic racetracks even in the absence of thermal fluctuations. The resulting depinning probability exhibits a robust sigmoidal current dependence, revealing a physical mechanism for probabilistic domain‐wall dynamics and highlighting the important role of fabrication ...

Micromagnetic simulation of nanoscale films with perpendicular anisotropy [PDF]

Journal of Applied Physics, 1997
A model is studied for the theoretical description of nanoscale magnetic films with high perpendicular anisotropy. In the model, the magnetic film is described in terms of single domain magnetic grains with Ising-like behavior, interacting via exchange as well as via dipolar forces.

Pyrochlore Artificial Spin Ice: Advances in Fabrication and Characterization of a 3D Magnetic Metamaterial

Small Structures, Volume 7, Issue 9, September 2026.
Pyrochlore artificial spin ice—a 3D magnetic metamaterial—is fabricated using two‐photon lithography and pyrolysis to create a polymer scaffold with a suitably small size that hosts tilted nanomagnets at different heights and orientations. Magnetic force microscopy reveals a variety of magnet states, while imaging with synchrotron X‐ray microscopy is ...
