Charge transfer governed interlayer magnetic coupling and symmetry breaking in a van der Waals magnet.
Article in Nature communications, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Van der Waals (vdW) magnets provide a rich landscape for innovative spintronic applications at atomic thickness. Among them, chromium sulfide bromide (CrSBr) stands out as a semiconducting antiferromagnet with the potential for magnetoelectric manipulation. However, the detection and electrical control of 2D magnetism in CrSBr are constrained by its centrosymmetric structure and in-plane antiferromagnetism. To address this challenge, we construct heterostructure devices composed of trilayer CrSBr and monolayer graphene, where interfacial charge transfer breaks the inversion symmetry of both magnetic order and crystallographic structure. The inversion symmetry breaking by charge transfer thus allows a full discrimination of the otherwise degenerate magnetic states using optical second harmonic generation, including the charge transfer induced intermediate magnetic states that consist of antiferromagnetic and ferromagnetic vdW interfaces. Furthermore, gate voltage enables the tuning of charge transfer, effectively modulating the interlayer magnetic coupling and magnetic transitions. Our findings deepen the understanding of optospintronic interaction and magnetoelectric manipulation in vdW magnets, paving the way for electrically tunable 2D spintronic devices.
