Mechanism of metallization and superconductivity suppression in YBa2(Cu0.97 Zn0.03)3 O6.92 revealed by 67Zn NQR
We measure the nuclear quadrupole resonance signal on the Zn site in nearly optimally doped YBa _2 Cu _3 O _6.92 , when Cu is substituted by 3% of isotopically pure ^67 Zn. We observe that Zn creates large insulating islands, confirming two earlier conjectures: that doping provokes an orbital transi...
