Critical-doping universality for cuprate superconductors: Oxygen nuclear-magnetic-resonance investigation of Ca(x)La(1-x)Ba(1.75-x)La(0.25+x)Cu(3)O(y)
cuprate superconductors Oxygen nuclear-magnetic-resonance investigation
2010/11/18
The critical doping levels in cuprates, where the ground state changes its nature (from an an-
tiferromagnet to a spin glass to superconductor to metal), are not universal. We investigate the origin ...
