Magnetoresistive detection of spin waves.
Article in Science advances, 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
We explore a detection method for spin waves consisting in integrating a magnetoresistive sensor on a magnonic waveguide. When subjected to the stray magnetic field generated by the spin wave, the relative orientation of the magnetizations of the two magnetic layers in the sensor oscillates in time, resulting in an electrical resistance change according to the so-called giant magnetoresistance effect. Upon application of an appropriate current bias, this variation of resistance translates into a sizable microwave voltage. At the submicrometer scale explored here, this signal is about 50 times larger than the one extracted from conventional inductive measurements of spin waves for comparable detection areas. Moreover, this detection scheme is expected to scale very favorably down to the nanometer size relevant for future magnon-based data processing architectures.
