Title:
MAGNETIC SENSOR ELEMENT, MAGNETIC SENSOR, AND MAGNETIC SENSOR DEVICE
Document Type and Number:
WIPO Patent Application WO/2022/208771
Kind Code:
A1
Abstract:
This magnetic sensor element (2) comprises a pin layer (21), a first non-magnetic layer (22), a first magnetic layer (23), and a free layer (24). The pin layer (21) has a fixed magnetization direction. The first non-magnetic layer (22) is stacked on the pin layer (21). The first magnetic layer (23) sandwiches the first non-magnetic layer (22) with the pin layer (21). The free layer (24) is disposed in the direction in which the pin layer (21) is superposed on the first non-magnetic layer (22). Each of the first magnetic layer (23) and the free layer (24) has a magnetization direction that changes more easily due to an external magnetic field than the pin layer (21). The pin layer (21) and the first magnetic layer (23) are coupled by an indirect exchange interaction.
