Giant magnetoresistance in the granular Co-Ag system
We report giant magnetoresistance (GMR) as much as 75% at 5 K and 24% at room
temperature in granular Co-Ag. We show that the GMR is isotropic and is the consequence
of the departure from ferromagnetic alignment of the Co particles. We have also determined
the resistivity component responsible for GMR and its temperature dependence.

Abstract
We report giant magnetoresistance (GMR) as much as 75% at 5 K and 24% at room temperature in granular Co-Ag. We show that the GMR is isotropic and is the consequence of the departure from ferromagnetic alignment of the Co particles. We have also determined the resistivity component responsible for GMR and its temperature dependence.
