Abstract:
Thin, horizontal-plane Hall sensors for read-head in magnetic recordings and methods for fabricating the sensor provide a novel sensor exhibiting high sensitivity and high spatial resolution.
Abstract:
Mesoscopic magnetic field sensors which can detect weak magnetic fields (typically 0.05 Tesla) over areas as small as tens of thousands of square nanometers (e.g. 40 nm×400 nm). The combination of enhanced magneto-resistance in an inhomogeneous high mobility semiconductor, having special electrode arrangements, with the use of island lithography, enables the production of special semiconductor/metal nano-composite structures, and has made possible the fabrication of an entirely new type of magnetic field sensor which exhibits very superior magneto-resistive behavior.
