While moderate disorder, induced thermally, depresses the critical temperature as a result of a reduced carrier concentration, strong oxygen disorder and chain fragmentation induced by low energy (80 keV) He^(+) irradiation suppresses the critical temperature beyond the values expected from the reduction of the carrier density. This provides an experimental evidence of pair breaking by chain disorder and outlines the importance of chain states in the pairing mechanism in the YBCO family. 1098-0121 10.1103/PhysRevB.68.094515 https://hdl.handle.net/20.500.14352/51442 http://dx.doi.org/10.1103/PhysRevB.68.094515 http://journals.aps.org/ Pair breaking by chain oxygen disorder in light-ion irradiated YBa_(2)Cu_(3)O_(x) thin films
