Electronic phase diagram of high-Tc cuprate superconductors from a mapping of the in-plane resistivity curvature.

We propose that resistivity curvature mapping (RCM) based on the in-plane resistivity data is a useful way to objectively draw electronic phase diagrams of high-Tc cuprates, where various crossovers are important. In particular, the pseudogap crossover line can be conveniently determined by RCM. We ... View More
