Iron-Based Superconductivity: A New Generation of High-Tc Materials

Johnpierre Paglione
University of Maryland

The stunning discovery of superconductivity in iron-based materials has uncovered a new family of high-temperature superconductors with properties that are both similar to and different than those of the copper-oxide family of superconductors. With transition temperatures approaching the boiling point of liquid nitrogen, these materials promise to provide a rich playground in which to study the fundamentals of superconductivity, while advancing the prospects for widespread technological applications.
