If you have a question about this talk, please contact Elizabeth Blackburn. In this talk I will give an overview of our research into the newly discovered iron-based superconductors. The work has two main threads. (1) Investigation of the normal state electronic structure using high field measurements of the de Haas-van Alphen effect, and (2) Investigation of the anisotropy of the superconducting energy gap using measurements of magnetic penetration depth. I will argue that the data suggest that there are two competing pairing channels in these materials – one which produces a gap with nodes and another which produces a fully gapped (nodeless) pairing state. It seems that these different pairing channels can both produce high Tc superconductivity. This talk is part of the Condensed Matter Physics Seminars series. This talk is included in these lists:
