Abstract

Competitive pressure Superconductivity often occurs in competition with other types of electronic order, such as antiferromagnetism. For some superconductors, the superconducting transition temperature can be maximized by forcing the critical temperature of the competing order down to zero. Xiao-Jia Chen et al. have now identified a related effect in a high-temperature superconductor, with the application of pressure yielding a striking two-step increase in the transition temperature. This points to a way of making higher transition temperatures through the suppression of the antiferromagnetic phase in the inner CuO2 plane, and the optimization of two competing energy scales (pairing and phase ordering) of different CuO2 planes.
