Abstract:

A series of studies in this laboratory has indicated that CuNO32.2.5H2O behaves approximately as an assembly of anti-ferromagnetically AF coupled pairs of Cu2 effective spin 12 ions. The Heisenberg binary pair system has a singlet ground state and a triplet excited state. Systematic discrepancies between theory and experiment have pointed to the necessity of including weak, AF, inter-pair interactions of a 1-D type. EPR studies have favored a magnetic ladder model structure. Modified author abstract
