On linear resistivity from  1 to 103 K in Sr2RuO4-δ single crystals grown by flux technique

We report transport measurements on single crystals of Sr2RuO4-δ, grown by the flux technique. The temperature dependence of the Hall coefficient is similar to the one measured in cuprates, and the linear resistivity persists up to  1000 K, while the superconductivity remains confined below 1 K. This suggests that the linear temperature dependence of resistivity is not an exclusive signature of the anomalous normal state of high-Tc cuprates but rather of layered oxides in general, especially single-layer perovskites, possibly independently of the magnitude of the superconducting temperature. In addition, such Sr2RuO4-δ may be used as a broad-range thermometer
