Decoding THz‐Driven Dynamic Fingerprints of Ferroelectric Nanotwin Networks
Advanced Materials, Volume 38, Issue 32, 8 June 2026.ABSTRACT Ultrafast polarization dynamics in ferroelectrics are of considerable interest for high‐speed tunable dielectrics and electro‐optics. Extended domain wall networks formed in ferroelectric twin nanodomains can support collective dynamics in the terahertz regime but require techniques that track polarization and strain evolution driven by ...

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.

Manipulating and trapping skyrmions by magnetic field gradients
New Journal of Physics, 2017 The effective manipulation of skyrmion motion introduces the technologically relevant possibility of skyrmion-based spintronics. Here we show how a magnetic skyrmion can be captured by a radially spatial gradient of the magnetic field.

Magnetic structure in the two‐dimensional van der Waals ferromagnet Fe3GaTe2
Journal of Applied Crystallography, Volume 59, Issue 3, Page 809-815, June 2026.High‐quality single crystals of Fe3GaTe2 were grown using the chemical vapour transport method, allowing for a precise determination of their crystal and magnetic structures. A shortening of the Fei–Fei distance enhances the Fe–Fe exchange interaction, providing a microscopic origin for its higher Curie temperature compared with Fe3GeTe2.High‐quality ...

Field-tuned spin excitation spectrum of kπ skyrmion
New Journal of Physics, 2019 We study spin wave excitation modes of kπ skyrmion ( k = 1, 2, 3) in a magnetic nanodot under an external magnetic field along the z direction using micromagnetic simulations based on the Landau–Lifshitz–Gilbert equation. We find that a transition of kπ

Current-driven coherent skyrmion generation
, 2019 The next-generation logic and memory devices using magnetic skyrmions as spintronic information carriers are frequently studied, thanks to their remarkable magnetic stability, extremely compact size and very-low-cost driving forces within nanotracks.
