CONFERENCE PROCEEDINGS FREE ACCESSThe induced anisotropy field H_k in very thin permalloy films sandwiched by Ta or Cu layers was investigated. The value of the H_k of Ta/Cu/Ni_79Fe_21/Cu/Ta film was found to decrease as the film thickness decreases below 20 nm. This H_k reduction is similar to that of the Ta/Ni_79Fe_21/Ta films indicating that the H_k reduction is independent of the surface energy or crystal structure of the seed layers. Thickness dependence of the film magnetostriction λ_<p-p> of theses films did not shows any clear correlation with that of H_k. This result indicates that the H_k reduction in thin films is not caused by the magnetostriction.View full abstractDownload PDF (558K) -

CONFERENCE PROCEEDINGS FREE ACCESSCrystallographic and magnetic properties are investigated for Co-Cr-Pt/Cr-Ti longitudinal media fabricated on MgO and Cr seedlayers prepared by Electron Cyclotron Resonance (ECR) sputtering method. The MgO and Cr layers deposited at room temperature show well developed {100} texture. Highly (100)-oriented Cr-Ti and (11.0)-oriented Co-Cr-Pt layers are epitaxially grown on the seedlayers. The ECR-deposite seedlayers are useful to prepare Co-Cr-Pt media with high coercivity and small crystal grain diameter.View full abstractDownload PDF (835K) -

CONFERENCE PROCEEDINGS FREE ACCESSThe magnetic and crystallographic characteristic of Co-Cr thin films deposited on pure Si(100), naturally oxidized SiO_2/Si and slide glass substrates were compared. Ta layer was examined for the underlayer of Co-Cr-Ta perpendicular recording layer. Pure Si(100) substrate was very effective to prepare Co-Cr thin films which had small grain size and their narrow distribution in the initial layer and higher perpendicular anisotropy energy K_u. And the perpendicular coercivityH_<c⊥> of Co-Cr-Ta layer deposited on Ta underlayer was improved in the Co-Cr-Ta layer thickness δ_<Co> below 50nm. Especially, by annealing in 500[℃] higher perpendicular anisotropy field Hk was attained.View full abstractDownload PDF (1017K) -

CONFERENCE PROCEEDINGS FREE ACCESSHigh density recording performance and thermal stability for super-fine particulate Ba-ferrite media were discussed. It was clarified that media made from smaller magnetic particles are effective for higher output in high density region. For smaller magnetic particle size, however, magnetization tends to be thermally unstable. Inter-particle interaction seems to affect thermal stability. In this paper, excellent recording capability for small particle media will first be discussed, then inter-particle interaction through ΔM, and thermal stability, in terms of magnetization time decay, will be discussed. Street-Woolley method and waiting time method are compared in estimating the activation volume for super-fine particulate media.View full abstractDownload PDF (717K) -
