摘要： A hybrid semiconductor-ferromagnet device is a device which has micromagnets (Co) deposited on semiconductor (InAs) two-dimensional electrons, and which has a junction structure of positive and negative magnetic field regions using a stray field resulting from the micromagnets. The magnetoresistance measured in the hybrid semiconductor-ferromagnet device has an asymmetrical hall resistance profile, and a change in magnetoresistance thereof is very large. The measured data is well consistent with the calculated results using a diffusive mode and a ballistic model.

摘要： A novel sensor element having low magnetic coercivity and an asymmetric hysteresis characteristic is formed by heating a strip of cobalt alloy in an exidizing atmosphere to form an oxide coating thereon and then the strip is cooled in the presence of a magnetic field of about 0.3 oersteds along its length. The strip is detected by subjecting it to an alternating magnetic interrogation field and passing the resulting magnetic disturbances through signal processing circuits which select pulses produced only once in each interrogation field cycle. The element is deactivated by subjecting it to a magnetic field which eliminates its asymmetry.
