Harness of room-temperature polar skyrmion bag in oxide superlattice.
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 1 paper.
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
Skyrmion bag is a higher-order skyrmion-based topological structure that can be used to reduce the risk of data loss in memory devices. It consists of an outer skyrmion wall and several inner skyrmions with opposite polarities. While skyrmion bags have been observed in ferromagnetic materials and liquid crystals, creating a polar skyrmion bag has proven challenging. Herein, we report the creation, evolution, and destruction of a polar skyrmion bag in a ferroelectric/dielectric oxide superlattice. The creation of a polar skyrmion bag is facilitated by applying an electric field pulse through a charged tip, which could be eliminated by changing the field direction. We also discover that the topological charge inside a polar skyrmion bag can be manipulated in situ by adjusting the magnitude of the applied potential. Through combined experimental observations and theoretical calculations, we have gained new insights into multipolar boundaries and identified promising prospects for future high-density, scalable, robust memory and low-loss nanoelectronics devices.
