Abstract

The normal-state transport properties are investigated for Sr ₂RuO₄ both in and out of the RuO₂ plane. It is shown that a quantitatively consistent explanation of ρ_ab and ρ_c 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 Q_i=(±0.6,± 0.6)π/a. In order to test this model, we suggest a pressure-dependent resistivity measurement to be performed.
