Abstract |
We have studied the transport and magnetic properties of a metallic granular CoxCu1-x system, with 0.2≤x≤0.25, prepared by using an ion-beam sputtering technique. Giant magnetoresistance (GMR) has been observed for the all studied concentration with the average amplitude around 2%. at 300K. The maximum value has been observed for Co21Cu79 granular alloy after annealing at 450°C for 2h. Above this concentration the MR decreases which is attributed to the percolation effect, which causes a concurrent reduction in magnetic coercivity. The variation of magnetic and transport properties with the concentration and annealing time is discussed. |
