Magnetometers
The MEMSIC magnetometers are specially designed to measure low gauss field range including the geomagnetic field domain. These magnetometers use AMR Permalloy film as magnetic field components. During manufacturing, a strong magnetic field is applied to the film to orient its magnetic domains in the same direction establishing a magnetizing vector that changes relative to the current flowing through the permalloy film changing the films resistance. This resistance variation is directly proportional to the angle between the magnetization vector and the current vector making the MEMSIC AMR sensor optimally designed to take advantage of this domain region.
