Abstract

We estimated the ratios of ⁶³Cu hyperfine coupling constants in the double-layer high-Tc superconductor HgBa₂CaCu₂O_6+δfrom the anisotropies in Cu nuclear spin-lattice relaxation rates and spin Knight shifts to study the nature of the ultraslow fluctuations causing the T₂anomaly 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.
