Magnetoresistance - Wikipedia
Magnetoresistance is the tendency of a material (often ferromagnetic) to change the value of its electrical resistance in an externally-applied magnetic field. There are a variety of effects that can be called magnetoresistance.
Magnetoresistance - an overview | ScienceDirect Topics
Magnetoresistance is the change of resistance with a magnetic field. The experimental use of magnetoresistance techniques to determine the Fermi surfaces of various metals has a long and successful history.
Of course, magnetoresistive effects exist when using other kinds of magnetic and non-magnetic materials but here we will only consider such materials marginally. Magnetic read heads, position sensors, earth magnetic field sensing, non-contact potentiometers, non-volatile memories, detection of biological activity (biosensors), spintronics,...
Magnetoresistance is a general term for the changes in the components of the resistivity and conductivity tensors of materials caused by the application of magnetic field. We are going to treat the magnetore-sistance of metals in a quite general and simple manner.

Tunnel magnetoresistance - Wikipedia
Tunnel magnetoresistance (TMR) is a magnetoresistive effect that occurs in a magnetic tunnel junction (MTJ), which is a component consisting of two ferromagnets separated by a thin insulator. If the insulating layer is thin enough (typically a few nanometres), electrons can tunnel from one ferromagnet into the other.
