Abstract
We unify the method of exchange perturbation theory for multicenter sy stems. For the case of exchange degeneracy in the total spin of the sy stem we give a secular equation that is more compact and convenient fo r calculations than those obtained earlier. On the basis of this forma lism we develop an algorithm for calculating the Heisenberg parameter for magnetic materials. Finally, we calculate the characteristics of a ntiferromagnetic transitions for the high-rr, materials La2 - xMeCuO4 and YBa2Cu3O6. (C) 1998 American Institute of Physics.
