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

open access: yesSmall Structures, Volume 7, Issue 7, July 2026.
Magnonic crystals (MCs) are an emerging class of metamaterial structures that manipulate spin‐wave propagation. This study identifies previously unknown, inverse‐designed MCs that achieve large magnonic bandgaps by combining a topology optimization framework with computational micromagnetics.

The Magnetic Mineralogy of Carbonaceous Chondrites: A Microscopy and Machine Learning Study of Meteorite WIS 91600

open access: yesGeochemistry, Geophysics, Geosystems, Volume 27, Issue 7, July 2026.
Abstract A central challenge in the paleomagnetic study of meteorites is to characterize their diverse remanence carriers. Here, we develop a machine‐learning assisted workflow that combines multi‐scale (mm to nm) and multi‐dimensional (2D‐3D) microscopy to build a comprehensive picture of ferromagnetic mineralogy in the C2 ungrouped carbonaceous ...

Exploring Curvature Effects in Direct‐Written 3D Curved Hollow Magnetic Nanoshells

open access: yesAdvanced Functional Materials, Volume 36, Issue 50, 22 June 2026.
Fabricated by a hybrid FEBID/CVD method, 3D PtC/Co3Fe core–shell heterostructures with engineered curvature and shell thickness exhibit complex reversal modes with axially symmetric N'eel‐type domain walls. XMCD‐PEEM combined with full‐scale micromagnetic simulations reveal how curvature and thickness govern the domain wall energy landscape and shape ...

Domain structure regularization in monocrystalline barium hexaferrite

open access: yesSemiconductor Physics, Quantum Electronics & Optoelectronics, 2018
Conditions for regular domain structure formation in a monocrystalline barium hexaferrite plate have been studied experimentally. The purpose of the work was to develop a simple and, at the same time, an effective method of regularizing the cylindrical ...

Theoretical analysis of transcranial magneto-acoustical stimulation with Hodgkin–Huxley neuron model

open access: yesFrontiers in Computational Neuroscience, 2016
Transcranial magneto-acoustical stimulation (TMAS) is a novel stimulation technology in which an ultrasonic wave within a magnetostatic field generates an electric current in an area of interest in the brain to modulate neuronal activities. As a key part

Observation of angle-dependent mode conversion and mode hopping in 2D annular antidot lattice

open access: yesScientific Reports, 2019
We report spin-wave excitations in annular antidot lattice fabricated from 15 nm-thin Ni80Fe20 film. The nanodots of 170 nm diameters are embedded in the 350 nm (diameter) antidot lattice to form the annular antidot lattice, which is arranged in a square

Electron Correlations in Local Effective Potential Theory

open access: yesComputation, 2016
Local effective potential theory, both stationary-state and time-dependent, constitutes the mapping from a system of electrons in an external field to one of the noninteracting fermions possessing the same basic variable such as the density, thereby ...
