Serendipitous vs. Systematic Search for Room-temperature Superconductivity
This article summarizes the results from a decade of research which began following a serendipitous discovery and continued with a systematic, Edisonian approach. During the serendipitous stage, there were indications of very-high-Tc superconductivity (at about 200–250 K) detected in laser-treated samples of doped strontium ruthenates. The synthesis route that had been used was strongly out of equilibrium. In spite of our intense studies, later, synthetic efforts along a route closer to equilibrium conditions did not reveal high-Tc superconductivity in the new samples, though there were indications of low-Tc superconductivity. Before the arrival of results on nonequilibrium synthetic routes, it is an appropriate time to summarize the results found within the equilibrium routes, analyze potential corollaries of the complex structure of samples within our initial findings, and discuss the next steps of research.
