摘要：

We review experimental results for SrCr(8-x)Ga(4+x)O19 (SCGO(X)), a system which includes Kagome layers of antiferromagnetically (AFM)-coupled Cr3+ ions. Even though the thermodynamic and inelastic neutron scattering measurements suggest a broken continuous symmetry, the AFM correlation length remains very short. Consideration of the possible ground states for xy AFM's on Kagome lattices provides a framework for understanding the observations on SCGO(x).
