| Popis: |
The minerals A2Cu3O(SO4)3 (A2=Na2, NaK, K2) constitute quantum spin systems with copper hexamers as basic structural units. Strong intra-hexamer spin couplings give rise to an effective triplet ground-state. Weak inter-hexamer spin couplings are responsible for two-dimensional long-range magnetic order in the (b,c)-plane below 3.0Comment: 19 pages, 6 figures, 3 tables |
