1 · What the graph read from it

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.

2 · The registry

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

Excitons are electronic excitations in semiconductors that mediate the interaction between light and matter. They underpin a wide range of phenomena from optoelectronics to nonlinear optics and sensors. Here we show that a bound exciton reservoir in the two-dimensional magnetic semiconductor CrSBr exerts a spin torque that coherently acts as damping-like and anti-damping-like torques. Crucially, this excitonic spin torque drives a non-trivial trajectory on the magnetic potential energy surface, enabling rapid and repeated switching between antiferromagnetic configurations from a single optical pulse. Unlike traditional spin torques that are fixed by heterostructure symmetry and interface design, this excitonic spin torque is an intrinsic material property. Our results establish excitons as a practical control knob for optospintronic devices, bidirectional quantum transducers, spintronic memory and studies of non-equilibrium magnetic phase transitions.
