Abstract

The normal-state transport properties are investigated for Sr2RuO4 both in and out of the RuO2 plane. It is shown that a quantitatively consistent explanation of ρab and ρc can be obtained by assuming that, in addition to the normal scattering of electrons by impurities and the electron-electron scattering, there is a strong coupling between the carriers of γ band and the incommensurate spin fluctuations peaked at Qi=(±0.6,±0.6)π/a. In order to test this model, we suggest a pressure-dependent resistivity measurement to be performed.
