Giant magnetoresistance (gmr) is a quantum mechanical magnetoresistance effect observed in multilayers composed of alternating ferromagnetic and non-magnetic conductive layers. Giant magnetoresistance ( gmr ) is a quantum mechanical magnetoresistance effect observed in multilayers composed of alternating ferromagnetic and non-magnetic conductive layers.
The giant magnetoresistance (gmr) is the large change in the electrical resistance which is induced by the application of a magnetic field to thin films composed of alternating ferromagnetic and nonmagnetic layers. In 1988 two solid-state physicists discovered that alternate ultra-thin layers of iron and chromium, each layer a few atoms thick, showed a very large drop in resistivity under an applied magnetic.
