Phase Separation, Competition, and Volume Fraction Control in NaFe${}_{1-x}$Co${}_x$As

Long Ma, J. Dai, P. S. Wang +9

We report a detailed nuclear magnetic resonance (NMR) study by combined ${}^{23}$Na and ${}^{75}$As measurements over a broad range of doping to map the phase diagram of NaFe${}_{1-x}$Co…
