摘要
The invention relates to magnetic sensor comprising a sensor element that is able to generate a spin-orbit torque (SOT). The SOT acts as a transverse bias field to set a proper working point for the sensor and so ensure that it responds linearly to an external field with maximized sensitivity. It also functions as a longitudinal bias field to suppress domain wall nucleation and propagation. The use of SOT effective field for biasing not only simplifies the sensor structure but also makes it possible to make an ultrathin and semi-transparent magnetic sensor.
