Fluctuation conductivity and pseudogap in single crystals under pressure with transport current flowing under an angle 45° to the twin boundaries.

Highlights: [•] The substitution of Y by Ho significantly affects the charge distribution. [•] The disordering in the oxygen subsystem which is affected by pressure. [•] Twin boundaries are effective scattering centers of normal carriers. [•] Near the conductivity is described by the Aslamasov–Larkin theory. [•] demonstrates two representative maxima which disappear under pressure. [ABSTRACT FROM AUTHOR]
