Perpendicular quantized magnetic disks with 45 Gbits on a 4 3 4 cm 2 area

چکیده
Quantized magnetic disks consisting of an array of single domain Ni pillars with a density of 18 Gbits/in. were fabricated using nanoimprint lithography ~NIL! and electroplating. The total disk area, limited by the NIL mold, is 4 cm34 cm, leading to a total 45 Gbits. Magnetic force microscope ~MFM! images show that all pillars 70 nm in diameter and 400 nm in height are single domain. The magnetostatic interaction between adjacent pillars is fairly strong. The pillars have an average switching field of 360 Oe and can be switched by a MFM tip with a large magnetic moment. © 1999 American Institute of Physics. @S0021-8979~99!66508-2#

Large area high density quantized magnetic disks fabricated using nanoimprint lithography
A new low-cost, high throughput method was developed for fabricating large area quantized magnetic disks ~QMDs! using nanoimprint lithography ~NIL!, electroplating, and chemical mechanical polishing. Perpendicular QMDs with a density of 18 Gbit/in. and good uniformity over an area of 4 cm34 cm ~total 45 Gbit! have been achieved, as well as longitudinal QMDs of 30 Gbit/in. The NIL molds for the ...

متن کاملPolarization of Fir Emission from T Tauri Disks
Recent observation of 850μm sub-mm polarization from T Tauri disks opens up the possibility of studying magnetic field structure within protostellar disks. The degree of polarization is around 3 % and the direction of polarization is perpendicular to the disk. Since thermal emission from dust grains dominates the spectral energy distribution at the sub-mm/FIR regime, dust grains are thought to ...
متن کاملSuperconductors of finite thickness in a perpendicular magnetic field: Strips and slabs.
The magnetic moment, flux and current penetration, and creep in type-II superconductors of nonzero thickness in a perpendicular applied magnetic field are calculated. The presented method extends previous onedimensional theories of thin strips and disks to the more realistic case of arbitrary thickness, including as limits the perpendicular geometry ~thin long strips and circular disks in a per...
متن کاملImpact of the MLC on the MRI field distortion of a prototype MRI-linac.
PURPOSE To cope with intrafraction tumor motion, integrated MRI-linac systems for real-time image guidance are currently under development. The multileaf collimator (MLC) is a key component in every state-of-the-art radiotherapy treatment system, allowing for accurate field shaping and tumor tracking. This work quantifies the magnetic impact of a widely used MLC on the MRI field homogeneity for...
