Abstract Interfacial magnetic anisotropy in Pt/Co1-xFex/Pt multilayer is tuned by doping iron atoms into cobalt layer. The perpendicular magnetic anisotropy and out-of-plane coercivity are found to decrease with x increasing. For a specific x, the out-of-plane coercivity acquires a maximal value as a function of the CoFe layer thickness. At low temperature, the coercivity is enhanced. Small coercivity but reasonably large perpendicular magnetic anisotropy can be obtained by controlling x and CoFe layer thickness.

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.
