Abstract
Stimulated by the magnetic behaviors of the title compounds we have developed a general treatment for solving an exchange-coupled Ising chain made up of three magnetic sublattices which are ordered according to the sequence A-B-A—C—A-B-A—C. Exact expressions of the susceptibility and specific heat are derived for Sa=Sb=½ and Sc=3-2, including a local anisotropy on the later sublattice, Dc. The magnetic properties of the CoCo(CoEDTA)2.4H2O compound are discussed on the basis of the developed model.Keywords
