我们报告的SrRuO 3，Sr 3Ru 2 O 7和CaRuO 3的传输测量的结果。在SrRuO 3和Sr 3Ru 2 O 7，我们的研究结果是一致的费米液体理论的预测，在以前的报告的基础上，样品更短的平均自由程。然而，在CaRuO 3中，在这里研究的高纯度样品的电阻率中看到T-1.5幂律。我们的工作提供了具体的证据，即使是金属状态的双烯酸盐是高度敏感的无序。
We report the results of transport measurements on SrRuO3, Sr3Ru2O7, and CaRuO3. In SrRuO3 and Sr3Ru2O7, our findings are consistent with the predictions of Fermi liquid theory, in contrast to previous reports based on samples with much shorter mean free paths. In CaRuO3, however, a T-1.5 power law is seen in the resistivity in the high purity samples studied here. Our work gives concrete evidence that even the metallic state of the ruthenates is highly sensitive to disorder.
