Abstract
We report a high-T Ga–NMR study in the Kagome-based anti-ferromagnetic compound SrCr9pGa12–9pO19 (0.81 <=p <=0.96), and present a refined mean-field analysis of the local NMR susceptibility of Cr-frustrated moments. We find that the intralayer Kagome coupling is J=86(6) K, and the interlayer coupling to non-Kagome Cr moments is Jʹ=69(7) K. The Jʹ / J=0.80(1) ratio confirms the common belief that the frustrated entity is a pyrochlore slab.
