MAGNETORESISTIVE SENSOR Russian patent published in 1996 - IPC

FIELD: automatic control; tachometers, displacement transducers, DC and ac magnetic field metering devices. SUBSTANCE: sensor has substrate covered, in sequence, with first magnetic film, separating film, conducting and protective layers; novelty is that additional protective layer of material identical in its physical and chemical properties to separating film material and resistant to effect of process for producing conducting layer configuration is made on surface of at least one of magnetic films opposite to separating film; thickness of additional protective layer does not exceed that of separating film. EFFECT: enlarged functional capabilities. 5 dwg
