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 tunnel junction (MTJ) used currently for data storage are characterized by perpendicular magnetic anisotropy, which is beneficial in terms of low current density required for switching and the thermal stability of the free magnetic layer. The other ferromagnet of MTJ, namely the reference layer is fixed using so-called synthetic antiferromagnetic (SAF) structure, which typically involves less-abundant material, such as Pt or Pd. We present an alternative stack structure, with the SAF based on Ni-Co superlattices, which is Pt-free. The reference layer of MTJ is characterized by the switching field above 250 mT. In MTJ nanopillars of diameter down to 80 nm, we show a robust switching with voltage pulses between 1 ms and 5 ns, tunneling magnetoresistance up to 140%, high thermal stability and switching current density of 2.6 MA/cm
