Popis: The influence of hydrostatic pressure up to 10 kbar on the superconducting transition temperature in doped single crystal of (Sr,Ca) 10 Cu 17 O 29 has been studied. A strong decrease of the normal state electrical resistivity and the pressure effect d T c /d P as high as 0.4 K/kbar were obtained. It is suggested that the superconductivity in the doped (Sr,Ca) 10 Cu 17 O 29 system is related to the inhomogeneous charge carrier distribution. The existence of quasi-one-dimensional (quasi-1D) metallic and spin-gapped regions in close electrical contact can explain the observed magnetic properties of (Sr,Ca) 10 Cu 17 O 29 and the effect of pressure on its transport properties.
