Abstract
We have succeeded in growing very high purity (99.995%) YBa2Cu3O7-delta crystals in BaZrO3 crucibles and have measured Delta-lambda(T) and Rs(T) at 1 GHz in crystals with various oxygen treatments. For an oxygen vacancy level of delta=0.007, Delta-lambda and Rs essentially reproduce our previous results and show no sign of the existence of the two order parameter components as recently reported by Srikanth et al. on BaZrO3-grown crystals. For other oxygen concentrations, we have in some cases observed deviations from the linear low T dependence of Delta-lambda, but never any sign of a second transition.
