    • The observation of multiple orbits and the experimental signal/noise necessitates performing the Fourier analysis for extracting m over a relatively wide range of B=20-60 T. This combined with the large Dingle temperatures we observe is known to lead to a systematic underestimate of m. We estimate this to be <20% for both mα and mγ.

    • Calculations were performed using an augmented plane wave plus local-orbital (APW+lo) code, WIEN2K (Ref.). For the results presented in this work, we used the experimental lattice coordinates and ionic positions and the LDA (Ref.) to the exchange-correlation potential. We included the spin-orbit interaction in both LDA and the GGA and the latter produces a higher magnetic moment, the electronic structure is sensitive to the magnitude of the moment and this, in turn, is very sensitive to the structure, specifically the height of the As atom above the Fe atom.
