$\mu$SR study of spin freezing and persistent spin dynamics in NaCaNi${}_2$F${}_7$

Y. Cai, M. N. Wilson, A. M. Hallas +8

A new pyrochlore compound, NaCaNi${}_2$F${}_7$, was recently synthesized and has a single magnetic site with spin-1 Ni${}^{2+}$. We present zero field (ZF) and longitudinal field (LF) mu…
