Linear resistivity from similar to 1 to 1050 K in Sr2RuO4-delta single crystals grown by the flux technique

We present the resistivity measurements on single crystals of Sr2RuO4-delta, grown by the flux technique. We discuss the striking, linear temperature dependence of resistivity that persists up to similar to 1050 K. The superconductivity in this system is confined below 1 K. This result suggests that the non-Fermi-liquid-alike linear temperature dependence of resistivity is not an exclusive signature of the anomalous normal stare of high-T-c cuprates but rather of layered oxides in general, especially perovskites, possibly independently of the magnitude of the superconducting temperature. In addition, such Sr2RuO4-delta samples, suitably optimized may be used as broad range thermometers.
