a change in the electrical resistance of a material exposed to a magnetic field.
Category: Electricity and Magnetism
Origin of magnetoresistance:
The change of electrical resistance produced in a conductor or semiconductor on application of a magnetic field.
Magnetoresistance is the property of a material to change the value of its electrical resistance when an external magnetic field is applied to it. The effect was first discovered by William Thomson in 1851, but he was unable to lower the electrical resistance of anything by more than 5%. This effect was later called ordinary magnetoresistance. More recent researchers discovered materials showing giant magnetoresistance, colossal magnetoresistance and magnetic tunnel effect. Generally, resistance can depend either on magnetization or on magnetic field directly.
