Abstract
Fluxgate sensors with cores made of etched sheets can be processed by applying a strong magnetic field in the direction normal to the sheet plane in order to reduce the sensor noise. Magnetic domain structure was observed by SEM. The treatment resulted in 40% reduction of fluxgate sensor noise. This study was performed on nanocrystalline materials, but similar technique can be used to process some amorphous and crystalline alloys. This technology can improve the performance of microfluxgate sensors.
