Longitudinal recording on FePt and FePtX (X = B, Ni) intermetallic compounds
Near field recording on high coercivity FePt intermetallic compound media using a high Bsat write element was investigated. Untextured FePt media were prepared by magnetron sputtering on ZrO2 disks at a substrate temperature ...
Low-frequency noise in spin valve sensors
Low frequency noise in giant magnetoresistive spin valves has been studied as a means of optimizing signal to noise ratios and characterizing device performance. The devices studied were sputter deposited NiFe/Cu/NiFe/FeMn ...
Microwave and optical sensor fusion for the shape extraction of three-dimensional space objects
Two sensors that have been proposed for use on a space robot are cameras and radar. Considered individually, neither of these sensors provides enough information for a computer to derive a good surface description of a ...
A thin film lithium niobate ferroelectric transistor
The incorporation of a thin film of LiNbO$\sb3$ in a conventional MOS (metal-oxide-semiconductor) structure gives the possibility of two fundamentally different types of computer memory architectures. One, based on ...
Magnetic recording on co-alloy perpendicular multilayers
Perpendicular recording has the potential to achieve high-density data storage. As the linear density approaches to the superparamagnetic limit, traditional longitudinal recording may give way to perpendicular recording. ...
Development of a 500 MW, one-microsecond, multi-kiloampere relativistic klystron amplifier
This work presents research on the one-microsecond, L-band relativistic klystron amplifier (RKA) project conducted at Los Alamos National Laboratory. A collection of theoretical analyses is presented for rf cavities, intense ...
