Abstract The structural and the magnetic properties of Gd2Fe16Cr compound are investigated by x-ray diffraction and magnetization measurements. The Gd2Fe16Cr compound has a rhombohedral Th2Zn17-type structure. There exist an anisotropic strong spontaneous magnetostriction and a negative thermal expansion in the magnetic state of Gd2Fe16Cr compound. The average thermal expansion coefficient /K in a temperature range of 294--454 K and /K in 454--572 K are obtained. The spontaneous magnetostrictive deformation and the Curie temperature are discussed.

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.
