Persistent Magnetism and Tunable Doping of Monolayer Graphene via Europium Density Modulation

open access: yesAdvanced Science, EarlyView.
The modulation of europium density at the graphene/rhenium interface enables electron doping of monolayer graphene both beneath and beyond the van Hove singularity. The interfacial europium is ferromagnetic, with a transition from a mixed Eu(II)/Eu(III) valence in the dense phase to a pure Eu(II) state in the diluted phase.

Room‐Temperature Magnetic Skyrmions and Intrinsic Anomalous Hall Effect in a Nodal‐Line Kagomé Ferromagnet MnRhP

open access: yesAdvanced Science, EarlyView.
MnRhP has been identified as a novel kagomé magnet that hosts magnetic skyrmions above room temperature and exhibits a large intrinsic anomalous Hall effect. The latter originates from Berry curvature associated with gapped nodal lines, establishing MnRhP as a promising platform for exploring high‐temperature topological phenomena in both real and ...

Expediting Desolvation–Diffusion Kinetics by Self‐Cascade Catalysis for Durable Low‐Temperature Zinc Metal Batteries

open access: yesAngewandte Chemie, EarlyView.
A novel self‐cascade catalytic strategy is proposed by designing an atomically dispersed Bi on deficient LaMnO3.15 perovskite (SABi/U‐LMO), serving as a promoter on subsequently lateral deposition of Zn enabled by interfacial electric field regulation.

Lithographically Controlled Liquid Metal Diffusion in Graphene: Fabrication and Magnetotransport Signatures of Superconductivity. [PDF]

open access: yesAdv Mater
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 ...

Tunable Negative Thermal Expansion in Fe/Cr‐Substituted Nd2Co17 Compounds via Magnetoelastic Coupling

open access: yesAdvanced Science, EarlyView.
This study achieves anisotropic thermal expansion tuning in Nd2(Co1‐xFex)17‐yCry compounds via a magnetoelastic strategy. Variable‐temperature synchrotron X‐ray diffraction reveals that increased Fe content induces switchable lattice responses. Compositional control reduces the volume expansion coefficient αV by 20% (x═0.7) and modulates TC (442–625 K),

Gossamer superconductivity

open access: yesPhilosophical Magazine, 2006
An new superconducting hamiltonian is introduced for which the exact ground state is the Anderson resonating valence bond. It differs from the t-J and hubbard hamiltonians in possessing a powerful attractive force. Its superconducting state is characterized by a full and intact d-wave tunneling gap, quasiparticle photoemission intensities that are ...

Intrinsic Negative Magnetoresistance and Broadband Photoresponse in Magnetic van der Waals Crystal TaFeTe2

open access: yesAdvanced Science, EarlyView.
2D van der Waals (vdW) materials MM′Te2 with broken symmetry attract great interest for unique magnetic structures and optical‐phonon‐induced phase transitions. We report mechanically exfoliable TaFeTe2 single crystals, exhibiting spin‐glass behavior, intrinsic unsaturated negative magnetoresistance up to 9 T, self‐powered internal photocurrent, and ...
