Strontium ruthenate is an oxide of Strontium and Ruthenium with the chemical formula Sr2RuO4. It was the first reported perovskite superconductor that did not contain copper.[1][2] Strontium ruthenate is structurally very similar to the high-temperature cuprate superconductors,[3] and in particular, is almost identical to the Lanthanum doped superconductor (La, Sr)2CuO4.[4] However, the transition temperature for the superconducting phase transition is 0.93 K, which is much lower than the corresponding value for cuprates.[1]
High-quality crystals Strontium ruthenate are synthesized using a floating zone method in a controlled atmosphere with Ruthenium as flux. The perovskite structure can be deduced based on powder x-ray diffraction measurements. Strontium ruthenate behaves as a conventional Fermi liquid at temperatures below 25 K.[2]
