摘要
We demonstrate that Pd/Co multilayers can have superior properties for perpendicular magnetic recording media using a contact probe head. The multilayers are capable of generating relatively large signal amplitudes compared to conventional perpendicular CoCrTa alloy media, with a more than twofold increase in signal amplitude at 145 kilo flux changes per inch. We have also investigated the effect of Cr alloying of the Co layer to reduce the demagnetization energy of the magnetic layer. Cr reduced both the demagnetizing energy of the magnetic layer and the surface anisotropy of the Pd/CoCr interface.
