Abstract
A magnetic sensor for sensing an external magnetic field includes first and second electrodes and first and second magnetic tunneling junctions. The first and second electrodes are disposed over a substrate; and the first and second magnetic tunneling junctions are conductively disposed between the first and second electrodes and connected in parallel between the first and second electrodes. The first and second magnetic tunneling junctions are arranged along a first easy axis of the magnetic sensor. The first magnetic tunneling junction includes a first pinned magnetization and a first free magnetization, and the second magnetic tunneling junction includes a second pinned magnetization and a second free magnetization. The first free magnetization and the second free magnetization are arranged substantially in parallel to the first easy axis and in substantially opposite directions.
