Description

The method of exchange perturbation theory for multicenter system is unified. For the case of exchange degeneration by total spin of system the secular equation is given in more compact and convenient form than obtained earlier. On the base of indicated formalism the algorithm for calculation of Heisenberg parameter for magnetic materials is suggested. For high-tc superconductors (La2-χMeCuO4 and YBa2Cu3O6) characteristics of antiferromagnetic transitions are calculated
