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

Strain engineering in skyrmion-hosting multilayers holds promising potential for spintronic devices. However, conventional strain is below 0.5%, limiting exploration of unique properties under substantial strain. In addition, while uniaxial strain modifies magnetic interactions anisotropically, its influence on skyrmions is underexplored. Here, we integrate skyrmion-hosting multilayers with a flexible liquid crystal film, enabling multistep skyrmion phase transitions through light-induced uniaxial strain up to 1%. Our results demonstrate that skyrmion transitions are sensitive to strain magnitude and orientation. Strain below 0.6% parallel to stripes transforms them into skyrmions. Above 0.6%, skyrmions elongate perpendicularly to the strain direction, exhibiting a negative Poisson effect, with deformation up to 40% at 0.8% strain. Further strain reverts skyrmions back into stripes. Micromagnetic simulations reveal that these phenomena stem from strain-induced anisotropic modulation of Dzyaloshinskii-Moriya interaction. This approach, which combines flexibility, light activation, and substantial uniaxial strain, offers a promising strategy for low-power, multistate spintronic devices.
