Increasing stripe-type fluctuations in $A$Fe${}_2$As${}_2$ ($A$ = K, Rb, Cs) superconductors probed by ${}^{75}$As NMR spectroscopy

Z. T. Zhang, D. Dmytriieva, S. Molatta +7

We report ${}^{75}$As nuclear magnetic resonance measurements on single crystals of RbFe${}_2$As${}_2$ and CsFe${}_2$As${}_2$. Taking previously reported results for KFe${}_2$As$_{2}…
