The antiferromagnetic cuboctahedron can serve as a paradigmatic example of certain frustrated anti ferromagnets. In addition it has the advantage that its complete energy spectrum can be obtained up to individual spin quantum numbers of s=3/2 (16777216 states). (C) 2008 Elsevier Ltd. All rights reserved. |
