| Abstract;This paper describes the results of our research on the development of micro and nano-Hall devices for monitoring ferromagnetic domains at the surfaces of magnetic recording media and garnets using our RT-SHPM. Micro-Hall probes were fabricated using a GaAs/AlGaAs heterostructure grown by MBE with a two dimensional electron gas density of 2x1011cm-2 and mobility of 400,000cm2/Vs, at 4.2K. The ways of increasing the carrier mobility of the polycrysalline bismuth films in order to improve the field sensitivity of the nano-Bi Hall probes were discussed. |
