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

Pure spin current enables the transport of spin information without charge flow, providing opportunities for next-generation information technologies. A pure spin current polarizer, capable of controlling both its transmittance and spin polarization, is critical for the development of spintronics; however, it has not yet been demonstrated. Here, we demonstrate a highly efficient pure spin current polarizer at room temperature using a single-domain antiferromagnetic insulator film, through structural engineering and spin-lattice coupling. Our device exhibits a large differential magnon current transmittance at room temperature. Remarkably, we find that the spin polarization of the transmitted magnon current aligns with the Néel vector of the polarizer. This enables a large modulation of damping-like torque and generation of out-of-plane-polarized magnon current, offering alternative routes for developing energy-efficient spintronic devices. We anticipate that this pure spin current polarizer will serve as a building block for spintronics based on pure spin current.
