摘要：

CoCrTa films deposited on fcc Pt and Au underlayers show excellent c-axis orientation. The 'epitaxial-growth' mechanism may explain the origin of such an effect. The perpendicular MOKE and VSM coercivity, shape of hysteresis loops and contact recording results of such media are investigated and discussed together with the film structure. A first peak D50 of 160 kFRPI has been realized by a single-layer Pt/CoCrTa rigid disk using an in-contact MIG head.
