|Title:||Origin of the A(1g) and B-1g electronic Raman scattering peaks in the superconducting state of YBa2Cu3O7-delta|
|Abstract:||The electronic Raman scattering was investigated in optimally oxygen-doped YBa2Cu3O7-delta single crystals as well in crystals doped with nonmagnetic, Zn2+ and magnetic Ni2+ impurities. We found that the intensity of the A(1g) peak is impurity independent and its energy to T-c ratio is nearly constant (2Delta/k(B)T(c)similar to5). Moreover, the signal at the B-1g channel is completely smeared out when nonmagnetic Zn2+ impurities are present. These results are discussed in terms of the current models of Devereaux , Venturini , and Zeyher and Greco.|
