Figure 6

The variation of change in R with B measured at 3 different Ts; 0.05 K (blue), 0.70 K (green) and 1.10 K (red) for w = (a) 24 nm (b) 48 nm and (c) 100 nm wire. The data are normalized with respect to zero B resistance [R(0)]. ΔR = [R − R(0)] is the change in R from R(0). The lines joining the data points are to guide the eye. (d) The variation of percentage change of MR with T for wires of w = 24 nm (blue), 48 nm (green) and 100 nm (red). The lines are to guide the eye.
