MAGNETIC FIELD INTENSITY MEASURING METHOD, MAGNETIC FIELD INTENSITY SENSOR, AND DIRECT CURRENT SENSOR

摘要

PROBLEM TO BE SOLVED: To highly sensitively and precisely evaluate a unidirectional magnetic field intensity, using an MR element, without complicating constitution, and to highly sensitively and precisely measure, for example, a direct current, using a direct current sensor.;SOLUTION: A resistance value change is detected under the condition where a magnetoresistive thin film 22 face is inclined at a prescribed angle θ with respect to a magnetic field-directional vertical face, in this magnetic measuring method for evaluating the unidirectional magnetic field Mx intensity, by detecting the resistance value change of a magnetoresistive thin film 22.;COPYRIGHT: (C)2009,JPO&INPIT
