We report on the noise performance characteristics of magnetic sensors using both magnetic tunnel junction (MTJ) and giant magnetoresistance (GMR) elements.
A magnetoresistive sensor uses the fact that the electrical resistance in a ferromagnetic thin film alloy is changed through an external magnetic field. “Ferrum ...
This paper reviews magnetoresistive sensors for detecting magnetic fields. These sensors are based on an effect which has been known for more than 100 years.
Sensors that monitor properties such as temperature, pressure, strain or flow provide an output signal that is directly related to the desired parameter.
