Easy‐Cone Magnetic State Induced Ultrahigh Sensitivity and Low Driving Current in Spin‐Orbit Coupling 3D Magnetic Sensors

Measurement of 3D vector magnetic field is of vital importance for the development of magnetic navigation, biomedical diagnosis, and microimaging. Traditional 3D magnetic sensors require cooperation of multiple sensors on three orthogonal planes, resulting in disadvantages of bulky size and low spat...
