a ρab(T) and ρc(T), and b the anisotropy ratio ρc/ρab(T), in zero field. The vertical dashed line indicates where SC correlations are established in the planes, resulting in the enhancement of the anisotropy; ρc continues to grow with decreasing T. c ρc/ρab vs. H⊥ at different T, as shown. Arrows show the positions of the anisotropy peak Hp, or the decoupling field, as well as Hb, where the anisotropy is enhanced. The method to determine Hb more precisely is described in Supplementary Fig. 1.
