Crystallographic 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...
متن کاملHigh Anisotropy CoPtCrB Magnetic Recording Media
We describe the synthesis, magnetism and structure of CoPtCrB alloys with Pt concentrations from 10 43 %. The Cr concentration in the alloys was 15-17 % and the B concentration was 9-11 %. The magnetic anisotropy and coercivity increase with increasing Pt up to M 30%, plateau at M 35,000 Oe and w 6000 Oe, respectively, and then decrease. Transmission electron microscopy results show the media f...
متن کاملQuantitative observation of magnetic flux distribution in new magnetic films for future high density recording media.
Off-axis electron holography was used to observe and quantify the magnetic microstructure of a perpendicular magnetic anisotropic (PMA) recording media. Thin foils of PMA materials exhibit an interesting up and down domain configuration. These domains are found to be very stable and were observed at the same time with their stray field, closing magnetic flux in the vacuum. The magnetic moment c...
متن کاملHigh Density Pcm Magnetic Tape Recording
The Bell & Howell Enhanced-NRZ recording reproducing technique for bit packing densities up to 40,000 per track inch is described in this paper. Utilization of the pulse code modulation format of Enhanced-NRZ achieves this high density with a bit error rate of one in ten million. Bell & Howell’s standard VR-3700B instrumentation tape recorder and wideband instrumentation recording tape are used...
متن کاملEffects 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...
