Left: the phase diagram of La2-pSrpCuO4 in zero external magnetic field (B = 0) shows no obvious connection between the antiferromagnetic (AFM) glass and pseudogap phases. Right: at magnetic fields sufficiently strong that superconductivity is suppressed, the AFM glass actually extends to the critical doping, p*~0.19, of the pseudogap phase, thereby revealing a hitherto hidden connection between the two phases.
