Abstract

PURPOSE: To obtain the optimum bias magnetic field by small currents, by gaining magnetic fields near to the optimum bias magnetic field by the remanence of a high, resistant magnetic-force film while adjusting divergence from the optimum bias magnetic field by magnetic fields generated by currents let flow to a conductive body.
CONSTITUTION: A high, resistant magnetic-force film 2 and a conductor film 7 are formed on a substrate 1 and etched. A magnetic resistance effect element consisting of stripes 4 and leads 5 is made up on a SiO2 film 3, electrode pads 6 are built up. Bias currents are introduced to the conductive layer 7 from the pads 6, and flow through a U-shaped conductor portion to generate bias magnetic fields. Meanwhile, sense currents are introduced from the one ends of the leads 5, are subject to the change of resistance being accompanied by the variation of the strength of external megnetism when the currents pass through the stripes 4 and detect the variation of the strength of external magnetism. Thus, bias can be adjusted by small currents because the remanence of the high, resistant magnetic-force film 2 is used for the bias magnetic fields, and the dispersion of bias conditions among elements can be eliminated.
