Title:
MAGNETIC SENSOR AND METHOD FOR MANUFACTURING MAGNETIC SENSOR
Document Type and Number:
Japanese Patent JP2022139920
Kind Code:
A
Abstract:
To increase output of a magnetic sensor.SOLUTION: A magnetic sensor 1 includes a ceramic substrate 2, a GMR layer 5, and an underlying layer 4. The ceramic substrate 2 includes a substrate body 20 and a grace layer 3. The substrate body 20 includes ceramic as a material. The grace layer 3 is formed in a surface of the substrate body 20. The GMR layer 5 has a laminate structure of a plurality of magnetic layers 6 and a plurality of non-magnetic layers 7. The underlying layer 4 is formed between the grace layer 3 and the GMR layer 5. The underlying layer 4 includes a BCC solid solution.SELECTED DRAWING: Figure 1
