Abstract :
In this paper, we analyzed the dispersion of grain boundary width in CoCrPt-SiO2 magnetic layer with various grain sizes deposited on a Ru underlayer. Also, we discuss the relation between the grain sizes of the magnetic layer and the underlayer. The CoCrPt-SiO2 magnetic layer was fabricated with rotating CoCrPt and SiO2 cathodes using a magnetron sputtering system with a thickness of 16 nm. The grain size of the magnetic layer was varied by adding oxygen to the sputtering argon gas. The grain boundary structure was analyzed with a Hitachi HF-2000 transmission electron microscope.
