Abstract To obtain information about the mechanism of high Tc superconductivity in YBa2Cu3O7-δ (YBCO) the dependence of Hall coefficient RH and electrical resistivity ρ on the temperature were studied in range from 77 to 300K. An inflexion point θ was found to exist around 130K in RH(T) and ρ(T) curves. Both the mobility μ and the concentration of the holes were evaluated above and below θ, separately. The μ of the holes dominant below θ was ten times greater than that above θ. The concentration of the heavy holes above θ was, however, one hundred times larger than that below θ. A discussion will be given in terms of the transport process of the holes drifting through P[sgrave]- and Pσ-orbits on the CuO2 planes in YBCO.
