Abstract
A magnetic field sensor based on the dependence of the magnetostrictive delay line (MDL) response on its biasing magnetic field is presented in this paper. Such a sensor can be formed in an integrated array measuring the distribution of field along the MDL axis. Experimental results are reported for amorphous FeSiB wire MDL´s, showing that high sensitivity and nonhysteresis are two advantages of this type of sensor
