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.Keywords
