MAGNETIC SENSOR AND METHOD OF MANUFACTURING THE SAME

摘要

PROBLEM TO BE SOLVED: To improve the detection accuracy of an external magnetic field by improving the temperature characteristics of a magnetic sensor using a magnetic tunneling effect element. SOLUTION: The magnetic sensor has magnetic tunneling effect elements 51, 52. The magnetization orientation of each fixed magnetization layer of these magnetic tunneling effect elements is set to be the same orientation (the orientation shown by the arrow) for each element. The magnetic sensor comprises a half-bridge circuit which retrieves the voltage across the element 52 as an output voltage Voutby serially connecting the element 51 and the elements 52 and by serially connecting a direct constant voltage source 53 to the element 51 and the element 52.
