Abstract

The magnetization and magnetotransport was measured in CoxAg1-x granular composites as a function of temperature and applied magnetic field. Transitions from blocked superparamagnetic behavior with increasing temperatures was observed in magnetization, giant magnetoresistence, and the extraordinary Hall effect measurements. It was found that the blocking temperature determined from magnetotransport measurements was lower than the one estimated from magnetic measurements due to magnetic scattering.
