Novel Method for Magnetic Field Vector Measurement Based on Dual-Axial Tunneling Magnetoresistive Sensors

We have prepared a dual-axial tunneling magnetoresistive (TMR) sensor for magnetic field vector measurement. Due to the measurement error caused by the crossfield effect, a theoretical single-domain model of magnetic tunneling junction was developed based on the Stoner-Wohlfarth model and utilized to depict the output characteristics of the sensor in a rotating external magnetic field in the linea...
