Reconfigurable Magnetotransport in MnBi2Te4 via Gate and Magnetic Field Tuning

Advanced Materials, EarlyView.
Gate‐tunable magnetoresistance sign reversal under in‐plane magnetic fields is observed in an ultrathin MnBi2Te4 device, arising from spin reorientation and distinct scattering mechanisms. Moreover, angular‐dependent measurements reveal clear gate‐controlled magnetotransport anisotropy, underscoring the strong coupling between gating, spin ...

Lithographically Controlled Liquid Metal Diffusion in Graphene: Fabrication and Magnetotransport Signatures of Superconductivity

Advanced Materials, EarlyView.
Lithography‐guided intercalation creates a proximitized 2D superconducting Ga layer under graphene Hall bars via liquid‐metal intercalation. The image shows a Hall bar where Ga atoms from the liquid phase enter through patterned intercalation channels beneath quasi‐freestanding bilayer graphene, forming a confined 2D metal that demonstrates ...

Tuning the Surface State and Zeta Potential of Aged CuO Nanoparticles by Additive‐Free Surface Treatments as Guided by XPS

Advanced Materials, EarlyView.
Aging of CuO nanoparticles (NP) involves a surface reconstruction induced by hydroxylation and concurrent organic‐O adsorption, which introduces O defects in the NP subsurface region. The defective surface results in a diffuse surface space region, as reflected by a low ζ‐potential of the aged NPs in ethanol solvent.

Observation of Topological Chirality Switching Induced Freezing of a Skyrmion Crystal

Advanced Materials, EarlyView.
Using Lorentz Transmission electron microscopy, it is shown that in the insulating van der Waals ferromagnet, CrBr3, a magnetic field can cause Bloch skyrmionic bubbles to spontaneously switch their chirality. As achiral type‐II bubbles are an intermediate state, the bubbles rapidly elongate and shrink when switching, thereby inducing a freezing of the
