In this continuation proposal we will conclude our muon study of FeCrAs, a recently re-examined material that displays many of the above characteristics, suggesting that it is a strongly correlated electron system, but with a local physics dominated by complex antiferromagnetism, magnetic frustration and charge fluctuations. By measuring a sample with a proven ultra-low degree of disorder, we will search for the proposed hidden spin-liquid phase in FeCrAs and measure the magnetic fluctuation spectrum over a wide temperature range.
