Abstract

Iron-based superconductors are a large family of materials that exhibit unconventional superconductivity that arises from antiferromagnetically-ordered parent compounds. One of the grand challenges in understanding the behavior of these materials is determining the physical mechanisms responsible for the transition into the superconducting state. We propose to use MuSR to tease apart the magnetic and superconducting orders in NaFeAs with Ni doping.
