Abstract Pd/CoMnSi (CMS)/Co/Pd multilayer films were designed based on the idea of combining highly spin-polarized materials with strong perpendicular magnetic anisotropy (PMA) films. The PMA of Pd/CMS/Co/Pd multilayer films was studied by optimizing the growth conditions and thickness of each film layer. The optimal structure of the multilayer films was Pd(6 nm)/CMS(5 nm)/Co(2 nm)/Pd(1 nm). Its abnormal Hall resistance (), coercivity () and effective magnetic anisotropy constant () are 0.08 , 284 Oe and 1.36 Merg/cm, respectively, which are 100%, 492%, and 183% higher than the corresponding values (0.04 , 48 Oe, and 0.48 Merg/cm) of the Pd(6 nm)/Co(1 nm)/Pd(3 nm) trilayer films. The analysis shows that the increases of the above values are the result of the Pd/CMS interface effect and CMS/Co interface ferromagnetic (FM) coupling, and that it is closely related to the thickness of each film layer in the multilayer films and the growth conditions of the multilayer films.

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.
