Programmable 2D Magnetic Clusterphenes With High Curie Temperature and Strong Magnetic Anisotropy via Cluster Assembly and Ligand Synergy

Advanced Functional Materials, EarlyView.
Programmable 2D magnetic clusterphenes are realized through a ligand‐mediated cluster‐assembly strategy. Direct linking of magnetic superatomic clusters enhances electron delocalization and symmetry breaking, enabling the concurrent strengthening of magnetic exchange interactions and spin–orbit coupling.

Impact of Disorder on Microscopic Superconducting and Normal‐State Responses in a Kagome Metal

Advanced Functional Materials, EarlyView.
Using depth‐resolved, field‐ and pressure‐dependent μSR$\umu{\rm SR}$ measurements, we show that disorder in Ta‐doped KV3Sb5 drives a crossover from nodal to nodeless superconductivity while strongly modifying the normal‐state magnetic response. Our results reveal that disorder affects superconductivity and magnetism in fundamentally different ways ...
