| Abstract(in English) | CoPtCr-SiO_2/Ru films were fabricated using FTS system aiming for the film for magnetic recording tape media. The Ar gas pressure in fabrication of magnetic layer and Ru underlayer had an influence on magnetic properties. Ru (001) texture was degraded at high Ar gas pressure in fabrication of underlayer. Coercivity and squareness ratio of the film were 4.3 kOe and 0.78, respectively. TEM observation implies that some CoPtCr columns with their diameter of 10nm, were grown on a Ru column with relatively large diameter of 20-50nm. Segregated structure was observed in the large agglomerated grains by SiO_2 grain boundary. |
