Abstract

We estimated the ratios of $^{63}$ Cu hyperfine coupling constants in the double-layer high- $T_{c}$ superconductor HgBa $_{2}$ CaCu $_{2}$ O $_{6 + δ}$ from the anisotropies in Cu nuclear spin-lattice relaxation rates and spin Knight shifts to study the nature of the ultraslow fluctuations causing the $T_{2}$ anomaly in the Cu nuclear spin-echo decay. The ultraslow fluctuations may come from uniform magnetic fluctuations spread around the wave vector $q$ = 0, otherwise the electric origins.
