Title:
MAGNETIC SENSOR AND METHOD FOR DETECTING MAGNETISM
Document Type and Number:
WIPO Patent Application WO/2022/230316
Kind Code:
A1
Abstract:
A magnetic sensor according to the present invention comprises a waveguide 1, a first electrode 2, a second electrode 3, and a detection electrode 4. On the waveguide 1, a first position 1A, a detection position 1C, and a second position 1B are aligned in the stated order. The first electrode 2 excites a first spin wave 21. The first spin wave 21 propagates from the first position 1A to the detection position 1C. The second electrode 3 excites a second spin wave 22. The second spin wave 22 propagates from the second position 1B to the detection position 1C. The detection electrode 4 extracts a signal from the detection position 1C.
