Spin freezing in the disordered pyrochlore magnet NaCaCo${}_2$F${}_7$: NMR studies and Monte-Carlo simulations

R. Sarkar, J. W. Krizan, F. Brückner +5

We present results of ${}^{23}$Na and ${}^{19}$F nuclear magnetic resonance (NMR) measurements on NaCaCo${}_2$F${}_7$, a frustrated pyrochlore magnet with a Curie-Weiss temperature, $T_{cw…
