MAGNETIC PROPERTIES OF CoCrPt THIN FILMS ON SELF-ASSEMBLED PS-PVP DIBLOCK COPOLYMER TEMPLATE

摘要

CoCrPt alloy films are attracting wide attention for applications to high-density magnetic recording media and hard magnetic layer in spin valve structure due to their high coercivity and strong magnetocrystalline anisotropy, Diblock copolymer templates are one of the most promising candidates for nanoscale patterning otherwise inaccessible by lithographic procedures [1]. In this study, we have investigated magnetic properties of Co{sub}68Cr{sub}18Pt{sub}14 thin films deposited on nanopatterend polystyrene(PS) -polyvinylpyridine (PVP) diblock copolymer.
