Abstract Ternary yttrium chromium sulfide, Y2CrS4, prepared by the solid-state reaction of Y2S3, Cr, and S, was found to exhibit an antiferromagnetic transition at about 64 K. The X-ray diffraction pattern at 300 K was refined with space group Pca21, and the structure parameters were determined to be a=12.51 Å, b=7.53 Å, and c=12.49 Å. We investigated the magnetotransport properties, and observed negative colossal magnetoresistance reaching up to 2.5$\times$104% in the semiconducting compound of Y2CrS4.

Online attention
Altmetric calculates a score based on the online attention an article receives. Each coloured thread in the circle represents a different type of online attention. The number in the centre is the Altmetric score. Social media and mainstream news media are the main sources that calculate the score. Reference managers such as Mendeley are also tracked but do not contribute to the score. Older articles often score higher because they have had more time to get noticed. To account for this, Altmetric has included the context data for other articles of a similar age.
