Discovery of BKT correlations in the quantum kagome compound Cs${}_2$Cu${}_3$SnF${}_{12}$

M. S. Grbić, I. Jakovac, I. Kupčić +2

We investigate the microscopic properties of the kagome compound Cs${}_2$Cu${}_3$SnF${}_{12}$ using ${}^{63,65}$Cu nuclear quadrupolar resonance (NQR). Analysis of the local hyperfine fiel…
