The normal-state transport properties of the La1.85-xSr0.15+xCu1-xMnxO4 system have been investigated by means of resistivity and thermoelectric power. The experimental results indicate that Mn doping induces a strong lattice deformation and leads to a gradual localization of the holes. The temperature-dependent resistivity and the broad peak in the S-T curve as well as the shift of the peak are discussed in terms of the change of crystal structure and d-p hybridization state.
