Interface‐Induced Stability of Nontrivial Topological Spin Textures: Unveiling Room‐Temperature Hopfions and Skyrmions

open access: yesAdvanced Materials, EarlyView.
The first room‐temperature, zero‐field observation of stable skyrmion–hopfion spin textures in EuS─Bi2Se3─EuS trilayers is reported. Combining Lorentz TEM imaging and micromagnetic modeling, the authors unveil how interfacial Dzyaloshinskii–Moriya interaction and geometric confinement stabilize these multidimensional topological states.

Independent Wavefront Multiplexing with Metasurfaces via Non‐Injective Transformation

open access: yesAdvanced Materials, EarlyView.
In this work, a universal metasurface multiplexing strategy is presented based on non‐injective transformation. By jointly optimizing two metasurfaces, multiplexed channels achieve independent wavefront control, overcoming crosstalk limits of single‐layer designs.

Magnetic Domain Texture in Fe3O4 Thin Films on SiO2 Nanospheres

open access: yesAdvanced Materials, EarlyView.
Fe3O4 thin films grown on ordered SiO2 nanospheres form curved nanocaps with 3D geometry, inducing magnetic domain texture. X‐ray spectromicroscopy (XMCD‐PEEM), cross‐sectional electron microscopy (STEM), and polarized grazing‐incidence small‐angle neutron scattering (GISANS) reveal how topography modulates magnetization.

Band Offsets from Angle‐Resolved Valence Band Photoemission Spectroscopy

open access: yesAdvanced Materials Interfaces, EarlyView.
Soft X‐ray Angle‐Resolved Photoemission Spectroscopy (SX‐ARPES) is employed to quantify conduction band offsets at semiconductor surfaces and interfaces by fitting valence band photoemission spectra. This method surpasses traditional techniques, providing accurate results for InAs and InSb systems.
