Abstract2.0nmCo/tnmRu$_{1-x}$Pd$_x$ multilayers with x=0, 0.05, 0.08, 0.24, 0.39 and 0.48 were prepared by magnetron sputtering. The spacer layer thickness of both Ru (before doping Pd) and RuPd (after doping Pd) varies from 0.2nm to 1.6nm. Two effects have been investigated: (1) the dependence of the interlayer coupling on the thickness of Ru$_{1-x}$Pd$_x$ as a function of x and (2) the dependence of the interlayer coupling on Pd doping density, x, as a function of thickness of Ru$_{1-x}$Pd$_x$. Our results indicate that the interlayer coupling is strongly dependent on the doping density and the spacer layer thickness. The saturation field $H_s$ increases when very low concentration of Pd doped in the Ru layers and a suitable spacer thickness are adopted.

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.
