Single-phase Bi2Sr2-xCuOy samples were synthesized by the conventional solid-state reaction method. The normal state transport properties and the behaviour of localized Cu2+ spins were investigated by means of resistivity, thermoelectric power and electron paramagnetic resonance. The experimental result shows that with the increase of the fraction of localized Cu2+ spins the resistivity increases rapidly and the broad maximum in the TEP curve shifts to high temperature. These results indicate that the variation of resistivity and TEP may be related to localized Cu2+ spin scattering.
