Abstract(in English) | We have investigated the effect of cross-sectional modulated boron segregation on Co/Pd multilayer perpendicular magnetic recording media in terms of the microstructure. Modulated contents of boron in depth profile in Co/Pd multilayer were successively achieved by controlling the process condition, especially richer boron contents in the seed layer than the magnetic layer. Microstructure analysis by a transmission electron microscopy (TEM) with high annular angle dark field (HAADF) detector and X-ray photoelectron spectroscopy (XPS) clearly showed that the boron content gradient provides boron diffusion not only in plane but also along cross-sectional direction of the magnetic layer. Observed magnetic properties suggested that this gradient diffusion support reduction of intergrain exchange coupling and improvement of the magnetic properties. |
