Chemical Doping Engineering of Polarization and Topological Textures in van der Waals Ferroelectric CuInP2S6

Advanced Science, Volume 13, Issue 16, 18 March 2026.
Our work reports that Li⁺ doping in CuInP2S₆ induces coexistence of high‐ and low‐polarization states, which fosters a rich spectrum of topological polar textures, such as bubbles and labyrinth domains. An unconventional flexoelectric effect is also discovered, where strain gradients can mechanically manipulate these polarization states and their ...

Mobile Néel skyrmions at room temperature: status and future

AIP Advances, 2016
Magnetic skyrmions are topologically protected spin textures that exhibit many fascinating features. As compared to the well-studied cryogenic Bloch skyrmions in bulk materials, we focus on the room-temperature Néel skyrmions in thin-film systems with an

Controlling Bubble and Skyrmion Lattice Order and Dynamics via Stripe Domain Engineering in Ferrimagnetic Fe/Gd Multilayers

Advanced Physics Research, Volume 5, Issue 3, March 2026.
The density and ordering of the bubble/skyrmion lattice hosted by Fe/Gd multilayers can be significantly enhanced using an in‐plane field to align the stripe domain state. As a result, the laser‐induced breathing mode dynamics are strongly modified, showing both an increased amplitude and frequency.

Magnetic skyrmions on a two-lane racetrack

New Journal of Physics, 2017
Magnetic skyrmions are particle-like textures in magnetization, characterized by a topological winding number. Nanometer-scale skyrmions have been observed at room temperature in magnetic multilayer structures.
