Evidence for two distinct energy scales in the Raman spectra of YBa2(CuNi)O6.95

Y. Gallais, A. Sacuto, P. Bourges +3

We report low energy electronic Raman scattering from Ni-substituted YBa2Cu3O6.95 single crystals with Tc ranging from 92.5 K to 78 K. The fully symmetrical A1g channel and the B1g…
