Figure 8

(a) Enlarged part of the in-plane electrical resistivity ρab (right vertical axis) and its derivative (left vertical axis) for x=0.05. (b) Data for x=0.07. The solid and dashed arrows indicate the structural phase transition temperature Ts and the antiferromagnetic transition temperature TN determined by NMR, respectively.
