NMR investigation of superconductivity and antiferromagnetism in CaFe${}_2$As${}_2$ under pressure

S. -H. Baek, H. Lee, S. E. Brown +5

We report ${}^{75}$As NMR measurements in CaFe${}_2$As${}_2$, made under applied pressures up to 0.83 GPa produced by a standard clamp pressure cell. Our data reveal phase segregation of…
