A Pt catalyst film with dendritic microcrystalline structure has been prepared by reducing PtO2 deposited by reactive sputtering. It is to be employed as the cathode catalyst of a polymer electrolyte fuel cell (PEFC). Despite using no support materia

The effects of the CrNiN pre-layer between the underlayer of Cr and the NiP/Al substrate on the microstructure and the micromagnetics of CoCrTa/Cr films were investigated. The CrNiN pre-layer with an amorphous-like phase enhanced H c of CoCrTa/Cr fil

The effects of differing thickness and Cr concentration of CoCrTa/Cr thin-film media for ultrahigh-density recording were studied with magnetic force microscopy (MFM). Although the remanence-thickness product Brδ increases linearly with magnetic lay

The relationship between the magnetic properties and the microstructures of amorphous CoSm films with a Cr underlayer has been investigated. A maximum Hc of 3500 OE was obtained at Sm = 15 at%. The temperature dependence of Hc was measured. Observati

A study of the magnetic properties and recording characteristics of C/CoCrTa/Cr film media as a function of CoCrTa thickness ( t Co ) is presented. The coercivity ( H c ) shows a broad peak around 250 A, but the B r δ product decreases linearly with

The electron-cyclotron-resonance (ECR) microwave plasma nitrogen or oxygen ions shower treatment on the NiP/Al substrates before sputtering leads to an increase in coercivity of CoCrTaPt/Cr isotropic media and a decrease in coercivity and OR of orien

We have found that higher coercivity can be achieved on CoCrTa/Cr films by introducing a CrNi pre-layer between underlayer Cr and NiP plated layer. Coercivity is dependent on the Ni content in CrNi layer, and shows a maximum at Ni=40at%. Comparing cr
