Switchable Magnonic Crystals Based on Spin Crossover/CrSBr Heterostructures
Advanced Materials, EarlyView.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 ...

Electric-field induced domain-wall dynamics: depinning and chirality switching
, 2013 We theoretically study the equilibrium and dynamic properties of nanoscale magnetic tunnel junctions (MTJs) and magnetic wires, in which an electric field controls the magnetic anisotropy through spin-orbit coupling.

Energetics and switching of quasi-uniform states in small ferromagnetic particles [PDF]
, 2004 We present a numerical algorithm to solve the micromagnetic equations based on tangential-plane minimization for the magnetization update and a homothethic-layer decomposition of outer space for the computation of the demagnetization field.

Micromagnetics of nanostructures [PDF]
Journal of Magnetism and Magnetic Materials, 2003 The results of numerical simulation of equilibrium magnetization patterns and magnetization reversal in flat cylindrical and elliptical particles of the soft magnetic type are discussed. It is found that the bending state originates in these particles due to instability of quasi-uniform magnetization at large enough in-plane sizes. Similar states exist

Resonant Domain Wall Dynamics in a Three‐Dimensional Magnetic Nano Double Helix
Advanced Materials, EarlyView.3D magnetic nanostructures promise exciting possibilities for magnetization dynamics. However, experimental realizations remain scarce. In nanoprinted cobalt double helices, time‐resolved X‐ray microscopy reveals harmonic domain wall dynamics. Simulations identify the mode and additional higher‐frequency resonances, revealing a rich dynamic landscape ...

On a decoupled linear FEM integrator for Eddy-current-LLG [PDF]
, 2013 We propose a numerical integrator for the coupled system of the eddy-current equation with the nonlinear Landau-Lifshitz-Gilbert equation. The considered effective field contains a general field contribution, and we particularly cover exchange ...

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.

Chiral magnet models and boundary condition geometry in Skyrmion electronics [PDF]
, 2017 Field theoretic techniques are used to relate (i) the Landau-Lifschitz approach to Skyrmion devices based on Dzyaloshinskii-Moriya (D-M) chiral magnets, and (ii) the mathematical approaches to quantum magnetism.

Advanced Science, EarlyView.This work proposes a high static magnetic field (HSMF) driven dual‐low‐dimension strategy for fabricating magnetic‐dielectric heterostructure (Fe3O4@MoS2) chains with programmable lengths. The constructed successive magnetic‐dielectric synergy, arising from uniaxial anisotropy‐enhanced magnetic response and abundant heterointerfaces that boost ...

Normal modes description of nonlinear ferromagnetic resonance for magnetic nanodots
AIP Advances, 2022 The spatially-inhomogeneous magnetization dynamics in a cylindrical magnetic nanodot driven by ac spin-torque is analyzed. To this end, the Landau-Lifshitz-Gilbert-Slonczewski equation is reformulated as a system of coupled nonlinear ordinary ...
