摘要：

dT(c)/dP of YBa2Cu4O8 single crystals has been measured up to 9 GPa under hydrostatic pressure. The large and positive initial value (dT(c)/dP)0 = 5.5 K/GPa is confirmed. T(c)(P) saturates above 5 GPa. Dramatic changes, in the T(c)(P) behavior are observed when the pressure is non-hydrostatic. They are caused by the twinning of the crystals. Opposite to the case of YBa2Cu3O7, the results for hydrostatic pressure are well reproducible. This is probably due to the well defined oxygen stoichiometry of YBa2Cu4O8 single crystals.
