چکیده
B2 ordered FeAl films with a small, uniform grain size have been produced by rf diode sputter deposition on glass substrates. CoCrPt films grown on FeAl underlayers were found to have the ~101̄0! lamellar texture. The in-plane coercivities (Hc) of the CoCrPt/FeAl films are comparable to those of the CoCrPt/Cr films and they can be further improved by inserting a thin Cr intermediate layer between the CoCrPt and the FeAl layers. By employing a MgO seed layer or a ~002! textured Cr seed layer, ~001! textured FeAl can be obtained. However, the ~001! FeAl underlayer only induces a weak ~112̄0! textured CoCrPt. Thus no improvement in Hc over those produced on unseeded FeAl underlayers was observed. © 1997 American Institute of Physics. @S0021-8979~97!36308-7#

MgO seed layers for CoCrPt/Cr longitudinal magnetic recording media
Sputter deposited MgO thin films with the B1 crystal structure and ~002! film texture are used as seed layers to improve the texture and magnetic properties of the CoCrPt/Cr magnetic thin films on glass substrates for longitudinal recording. The desired ~002! textured Cr underlayers are usually obtained by sputtering Cr onto heated substrates. However, it is found that the MgO seed layers can i...
متن کاملHigh 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...
متن کاملNew Ni5Al3 Underlayer for Longitudinal Magnetic Recording Media
We describe a new Ni5Al3 underlayer for high-density longitudinal magnetic recording. The Ni5Al3 underlayer has the FCC derivative Ga3Pt5 structure. The Ni5Al3 (221) plane has good lattice match with the CoCrPt (10 1 0) plane. In addition, unlike the NiAl (112) plane, the Ni5Al3 (221) plane has the lowest surface energy. Hence, the Ni5Al3 thin film has a strong (221) texture and can induce CoCr...
متن کاملControlling 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...
متن کاملExperimental 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...
