Europium discovery
 New element found to be a superconductor

May 18,
2009 --
Of the 92 naturally occurring elements, add another to the list of those that are superconductors. James S. Schilling, Ph.D., professor of physics in Arts & Sciences at Washington University in St. Louis, and Mathew Debessai, Ph.D., — Schilling's doctoral student at the time — discovered that europium becomes superconducting at 1.8 K (-456 °F) and 80 GPa (790,000 atmospheres) of pressure, making it the 53rd known elemental superconductor and the 23rd at high pressure.

Additional Background: The primary thrust of the research in Professor Schilling's group is to study the influence of high hydrostatic pressure on the superconducting, magnetic and structural properties of exotic condensed matter systems. In this regard the application of pressure is used to test their understanding of interesting physical phenomena as a function of lattice parameter, to search for new phenomena in solids, as well as, in combination with high temperatures, to synthesize new materials unavailable under ambient pressure conditions. His group is currently focusing its research on the properties of the recently discovered (January 2001) high-temperature superconductor MgB2, oxygen ordering effects in the high-Tc oxide superconductors, and superconductivity/magnetism in low-dimensional organic solids.
