Ferromagnetic Spin Fluctuation and Unconventional Superconductivity in Rb${}_2$Cr${}_3$As${}_3$ revealed by ${}^{75}$As NMR and NQR

J. Yang, Z. T. Tang, G. H. Cao +1

We report ${}^{75}$As nuclear magnetic resonance (NMR) and nuclear quadrupole resonance (NQR) studies on the superconductor Rb${}_2$Cr${}_3$As${}_3$ with a quasi one-dimensional crys…
