Competing orders suppressed by disorder around a hidden quantum critical point in cuprate high Tc superconductors
S. Sanna, F. Coneri. A. Rigoldi, G. Concas +2
We report extensive muon spin rotation measurements on the lightly doped Y1-xCaxBa2Cu3O6+y compound, which allows us to disentangle the effect of disorder, controlled by random Ca2…

Evidence of two distinct charge carriers in underdoped high Tc cuprates
S. Sanna, F. Coneri, A. Rigoldi +2
We present results on heavily underdoped Y_1-xCa_xBa_2Cu_3O_6+y which provide the evidence that the doping mechanism (cation substitution or oxygen loading) directly determines whe…
