METHOD REDUCING EFFECT OF HYSTERESIS ON RESULTS OF MEASUREMENT OF MAGNETIC FIELD Russian patent published in 2000 - IPC

Abstract RU 2152046 C1

FIELD: measurement of magnetic field. SUBSTANCE: method can be used in thin-film multilayer magnetoresistive pickups and reading heads. Before measurement magnetosensitive elements of magnetoresistive pickup are exposed to effect of auxiliary pulse magnetic field. Magnetic field has same value in all magnetosensitive elements of magnetoresistive pickup and exceeds preset maximum value of measured magnetic field. Auxiliary pulse magnetic field is directed transverse to axis of light magnetization of multilayer magnetoresistive pickup. EFFECT: reduced effect of hysteresis on results of measurement of magnetic field by multilayer magnetoresistive pickup. 3 dwg
