Title:
MAGNETIC SENSOR
Document Type and Number:
WIPO Patent Application WO/2018/008525
Kind Code:
A1
Abstract:
A magnetic sensor (1) is provided with: a substrate (2) that has a main surface (21); a free layer (3) that has an magnetic easy-axis direction which is an in-plane direction parallel to the main surface; an intermediate layer (4) that is provided between the substrate and the free layer; and a fixed layer (5) that is provided between the substrate and the intermediate layer. The fixed layer has: a first ferromagnetic layer (51), the magnetization direction of which is fixed in a first direction nonparallel to the main surface; a second ferromagnetic layer (52), the magnetization direction of which is fixed in a second direction in which a component of a direction parallel to the normal line of the main surface is opposed to the first direction; and a nonmagnetic layer (53) that is provided between the first ferromagnetic layer and the second ferromagnetic layer.
