Magnetoresistive sensors based on the elasticity of domain walls

examples based on this mechanism are given and are verified via micromagnetic simulation. Devices based on this mechanism may greatly improve the performance and integration level of the 3-axis magnetic sensor. II. Concept and mechanism In some soft magnetic materials, such as the CoFeB-MgO thin films, the intrinsic pinning field has been

simulation results [12]. PCB with MR sensor array and electronics is fixed perpendicular to the PCB with emitter coils (Fig.2). The MR sensing elements are placed exactly in the center between two coils to avoid direct coupling. With that configuration, MR elements are sensitive to the normal component of the magnetic field. To further reduce
