MAGNETORESISTIVE TRANSDUCER Russian patent published in 2001 - IPC

FIELD: automatic control; tachometers, non-destructive test equipment, displacement transducers for dc and ac field and current measurements. SUBSTANCE: novelty in magnetoresistive transducer is that thin-film magnetic structure built up of at least one magnetic field is placed above control conductor. Thin-film magnetic structure may be built up of two magnetic films with high-resistance thin-film nonmagnetic interlayer in-between. EFFECT: reduced control current through conductor which decreases input power and heating and increases sensitivity. 2 cl, 4 dwg
