Creating zero-field skyrmions in exchange-biased multilayers through X-ray illumination

open access: yesNature Communications, 2020
Skyrmions are objects with whirled magnetization protected by their topology that can be created by different means, however, without control of their position. Here, the authors present a method exploiting x-rays to create skyrmions at the beam position

General phase-structure relationship in polar rod-shaped liquid crystals: Importance of shape anisotropy and dipolar strength

open access: yesGiant, 2022
Ferroelectricity is a property with spontaneous polarization, which is of paramount importance in modern electrooptic applications. Yet, its observations are mostly limited to solids or chiral smectic C liquid crystals with nearly no fluidity.
