Output Characteristics of Two-Dimensional Spin Valve Chip

This paper investigated the output characteristics of a two-dimensional spin valve chip. The chip was placed in a series of rotating magnetic fields. The output relation curve of the two-dimensional spin valve chip transformed from a circle-like shape to a diamond-like shape with increasing magnetic field intensity because of the influence of the field perpendicular to the sensing axis. The experimental results fitted well with the simulation results. The output characteristics of the two-dimensional spin valve chip can be used to measure the direction of the magnetic fields.
