Tri-Hexagonal charge order in kagome metal CsV${}_3$Sb${}_5$ revealed by ${}^{121}$Sb NQR

Chao Mu, Qiangwei Yin, Zhijun Tu +5

We report ${}^{121}$Sb nuclear quadrupole resonance (NQR) measurements on kagome superconductor CsV${}_3$Sb${}_5$ with $T_{\mathrm{c}}=2.5$ K. ${}^{121}$Sb NQR spectra split after a charge dens…
