Ga NMR study of the local susceptibility in SrCr8Ga4O19: pseudogap and paramagnetic defects

P. Mendels, A. Keren, L. Limot +3

We present the first Ga(4f) NMR study of the Cr susceptibility in the archetype of Kagome based frustrated antiferromagnets, SrCr${}_8$Ga${}_4$O${}_{19}$. Our major finding is that t…
