Experiments show that the application of a magnetic field increases the resistivity of a semiconductor and produces a decrease in the magnitude of the Hall ...
The phenomenon of the change of conductivity by the applied magnetic field is generically called a magnetoresistance effect. The contents are divided into the ...
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.
They detect changes, or disturbances in magnetic fields that have been created or modified by objects or events. The magnetic fields may therefore carry ...
