چکیده

We have investigated the magnetic and structural properties of CoCrPt perpendicular films with respect to in situ interdiffusion of CrMn from top layers. We have observed a coercivity of 5700 Oe in the films with a thin CrMn overlayer, which is greater than two times larger than the similar type of films without a CrMn overlayer. This increment is attributed to the decoupling of grains by diffusion of CrMn from top layer through the grain boundaries.

Controlling the magnetic properties of CoCrPt thin films by means of thin hexagonal-close-packed intermediate layers

CoCrPt films for longitudinal recording media were investigated as a function of substrate bias applied during the deposition. CoCrPt films were deposited on an underlayer stack consisting of glass/NiAl/CrMn with bias applied only during deposition of the CoCrPt layer. A strong dependence of the CoCrPt coercivity on the substrate bias was observed when a thin hexagonal-close-packed CoCrTa templ...

Highly oriented perpendicular Co-alloy media on Si„111... substrates

CoCrPt/Ti/Ag films with the easy axes of the hexagonal-closed-pack Co grains perpendicular to the film plane were epitaxially grown on HF-etched Si~111! single crystal substrates by rf sputter deposition. The orientation relationship was determined by x-ray pole figure measurements and transmission electron microscopy to be CoCrPt~0001!@101̄0#iTi~0001!@101̄0#iAg~111!@112̄# 3iSi~111!@112̄#. The magn...

Experimental modeling of intergranular exchange coupling for perpendicular thin film media

We present an experimental model system that enables quantitative assessment of intergranular exchange coupling in CoCrPt-oxide perpendicular magnetic recording media. A thin film structure consisting of a high coercivity CoPt unicrystal layer and a lower coercivity CoPt layer separated by a thin oxide interlayer is used to model perpendicularly magnetized grains separated by oxide grain bounda...

High Coercivity Co-Alloy Thin Films on Polymer Substrates

Films of (10 10) textured CoCrPt have been sputtered on polymer substrates for use as thin film tape media. Underlayers of NiAl combined with various intermediate layers were employed to obtain this orientation without thermal damage to the polymer. It was found that NiAl underlayers sputtered on tape substrates have a (112) growth texture, like they do on glass. Film coercivity varied as a fun...

Improvement of preferred orientation of NiAlÕCrMn underlayers deposited on prebaked tape substrates

It was observed that the coercivity of CoCrPt films deposited on a polyimide tape was much lower than the coercivity deposited on a rigid glass substrate under identical conditions. X-ray diffraction showed that the desirable ~112! and ~110! texture of the NiAl/CrMn underlayers on the tape substrate was severely degraded during the deposition process. This resulted in the destruction of ~10.0! ...
