Abstract

A Ti intermediate layer between permalloy and Co-Cr-Nb-Pt storage layer improved the magnetic properties of double layered media. Cr segregation, Ni and Co enrichment was found within the Ti layer by AES. XTEM study revealed reduced crystallite size of Co-Cr-Nb-Pt due to nucleation in an amorphous phase formed as a result of a chemical interaction at the interface of the Ti and permalloy layers.
