Abstract
In this Paper Giant magnetoresistance (GMR) is a quantum mechanical magnetoresistance impact saw in slight film structures made out of substituting ferromagnetic and nonmagnetic layers. The impact shows itself as a noteworthy reduction (normally 10–80%) in electrical obstruction within the sight of an attractive field. The impact is abused financially by makers of hard circle drives.
