Hydrostatic-pressure effects on the pseudogap in slightly doped YBa2Cu3O7-δ single crystals

A. L. Solovjov, L. V. Omelchenko, R. V. Vovk +2

The influence of hydrostatic pressure up to P=1.05 GPa on resistivity R, excess conductivity ${\sigma }^{\prime }(T)$ and pseudogap $\Delta \ast (T)$ is studied in slightly doped single crystals of YBa2Cu3O7…
