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

Magnetic impurities in a non-magnetic metal are screened by conduction electrons, forming a spin cloud known as a Kondo cloud. Experimental detection of this Kondo screening cloud in dilute magnetic alloys remains challenging. Here we show evidence of Kondo clouds and their coupling in devices composed of mirror-symmetric carbon nanotube arrays separated by a molybdenum strip. The Kondo effect in these devices depends sensitively on the width of the molybdenum strip. For widths of 0.3-1.2 micrometers and 1.5-3.0 micrometers, the Kondo temperature forms two plateaus at about 107.8 kelvin and 15.8 kelvin, respectively. These results are explained by the formation of Kondo clouds and by intra-edge and inter-edge coupling within molybdenum. Calculations based on a two-spin model reproduce the two plateaus and their crossover. These findings may open opportunities for applications in spintronics and quantum computing.
