Effect of magnetic fluctuations on the normal-state properties of$\ab{Sr_2RuO_4}

We investigate the normal-state transport properties of $\ab{Sr_2RuO_4}$ and we show that a consistent explanation of the experimental results can be obtained assuming that the system is near a quantum phase transition. Within the framework of a self-consistent spin fluctuation theory, we calculate...

Description
Summary:We investigate the normal-state transport properties of $\ab{Sr_2RuO_4}$ and we show that a consistent explanation of the experimental results can be obtained assuming that the system is near a quantum phase transition. Within the framework of a self-consistent spin fluctuation theory, we calculate the temperature variation of some relevant physical quantities and we discuss a possible microscopic origin of the quantum phase transition.
