Characterization to realize CoCr-based perpendicular magnetic recording media with high squareness and normalized coercivity

Abstract

Effects of intermediate layers on magnetic properties and read/write performance in CoCrPt perpendicular recording media with an FeHfN soft magnetic underlayer

Effects of utilizing a granular nucleation layer on magnetic properties and microstructure of CoPt–B2O3 granular medium

“…Theoretically, H c =H k should be unity when there is no reduction in H c . 30) For the introduction of the NL with WO 3 and TiO 2 , H c =H k increases from 0.45 to 0.54 at d NL of 3 and 2 respectively. For the NL with ZrO 2 , H c =H k shows the peak of 0.51 at d NL of 1 nm, indicating that granular media with high H c =H k values of more than 0.5 can be realized by introducing such an NL.…”
