Title:
MAGNETISM DETECTING DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/053536
Kind Code:
A1
Abstract:
The present invention suppresses a degradation in detection accuracy. This magnetism detecting device comprises a magnetoresistive element (10) and a detecting unit (109) that detects an external magnetic field on the basis of a resistance value of the magnetoresistive element. The magnetoresistive element comprises a fixed layer (11) in which the magnetizing direction is fixed, a non-magnetic layer (12) disposed on the fixed layer, and a free layer (13) that is disposed on the non-magnetic layer and the magnetizing direction of which changes over time, the magnetic anisotropic axis of the free layer being parallel to the magnetizing direction of the fixed layer.
