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

Magnons are quantized collective excitations of long-range ordered spins. At nanometre wavelengths, exchange interactions increasingly govern their dynamics, giving rise to a largely unexplored regime of couplings between magnons and other quasi-particles; however, detecting such short-wavelength spin waves has remained a key experimental challenge. Here we introduce magnon momentum microscopy-a quasi-elastic, resonant magnetic soft-X-ray scattering technique that directly images magnon populations across two-dimensional momentum space. Owing to its remarkable sensitivity, it can capture nonlinear magnon interactions over large regions of the dispersion plane. We apply magnon momentum microscopy to the prototypical magnonic material yttrium iron garnet and reveal a rich variety of previously unobserved nonlinear magnon interactions. With its element specificity and bulk sensitivity, as well as intrinsic access to nanometre-scale wavelengths without frequency limitation, this technique establishes a powerful and versatile platform for exploring short-wavelength and nonlinear magnonics.
