The motion of magnetic skyrmions driven by propagating spin waves (SWs) in a skyrmion-based magnetic nanotrack is investigated by means of micromagnetic simulation. It is found that the propagating SWs can drive the skyrmion into a stream motion. The velocity of the skyrmion motion is controlled by the changes of SWs frequency and exciting field amplitude, which is sensitive to the size of skyrmion.
An embedded tri-axial magnetometer of high precision based on AMR (Anisotropy Magnetic Resistance) sensor was designed and achieved in this paper. For purpose of avoiding ferromagnetic disturbances to magnetic sensor, this device applied the manner of separating the sensor and signal processing terminal. By theoretically analyzing main errors of the magnetometer, compensation model was established,...
