What is Magnetoresistivity and Magnetoresistors?

Magnetoresistivity is the phenomena of change of resistivity of some metals and semiconductor when it is exposed to external magnetic field. This phenomenon is observed at low temperature. The material which possesses magnetoresistivety are called Magnetoresistors. Magnetoresistivity is observed due to lengthening of path of moving electron when it experiences a force due to external … Read more
