K. Alex Müller and Georg Bednorz found evidence for superconductivity in copper-oxide compounds at unexpectedly high temperatures. Their 1986 barium-lanthanum-copper-oxygen samples contained multiple phases and showed a large electrical resistivity drop with onset in the 30 kelvin range. The strong dependence on applied current and sample connectivity required cautious interpretation. This initial result redirected the search for high-temperature superconductors toward chemically complex oxides.[ref]
