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.
