Effects of Stoichiometry on the Magnetic and Structural Properties of Perpendicular Barium Ferrite Thin Film Media
The effects of stoichiometry factor on the magnetic and structural properties of perpendicular barium ferrite thin films with composition of BaO (Fe2O3) were systematically investigated. Within the range 2 2 6, the -axis for barium ferrite thin films can be oriented perpendicularly by the use of Pt underlayer and with optimized processing conditions. Perpendicular -axis orientation becomes wors...
متن کاملBarium and Strontium Ferrite Perpendicular Thin Film Media with a Sendust Soft Magnetic Underlayer
The possibility of using sendust (FeAlSi) as the soft magnetic underlayer for hexagonal barium ferrite (BaM) and strontium ferrite (SrM) was studied. Sendust films were found to retain their soft magnetic properties with a rapid thermal anneal (RTA) at 800 C for 60 s, which is necessary to crystallize the as-deposited amorphous BaM and SrM films. Several film structures with sendust films as th...
متن کاملMagnetic Layers for Perpendicular Recording Media
Hard disk drives (HDDs) are recently being incorporated into video recorders, car navigation devices, family game machines, etc., as devices (AV-HDDs) to store digital AV (audio-visual) information such as movies and television programs. Because the AV-HDD has the features of large capacity, high speed and low cost, it is suitable for long-time recording, high-speed random access and multi-chan...
متن کاملMagnetic structures in Co-Cr media for perpendicular magnetic recording
High bit densities have been demonstrated in longitudinal as well as in perpendicular magnetic recording. For the latter an area density of more than 12 G b i t / i n 2 has been obtained in a sputtered C o C r T a hard disk with a soft magnetic underlayer recorded with a special single pole head. In this paper the role of microstructure and morphology in relation to the compositional separation...
متن کاملCrystallographic and Magnetic Characteristics of Ba Ferrite Sputtered Films for High Density Magnetic Recording Disks
Ba ferrite films with non-stoichiometric composition were deposited using Facing Targets Sputtering apparatus. The films with well c-axis orientation and remarkable perpendicular anisotropy were attained even at the substrate temperature below 600°C. Sufficiently large saturation magnetization 4 w o f 3.7 kGand small crystallite size below 20 nm were attained using the targets with Fe-excessive...
