| Abstract | The EPR g factors, g(parallel to) and g(perpendicular to), of Co2+ and hyperfine structure constants (A(parallel to), A(perpendicular to)) of Co-59(2+) and (60)Co2(+) isotopes in both trigonal Mg2+ sites of La2Mg3(NO3)(12).24H(2)O crystal are calculated from the high-order perturbation formulas of EPR parameters based on the cluster approach for 3d(7) ion. It is found that to explain reasonably all these EPR parameters, the local relaxation effects (particularly, those related to the trigonal distortion angles theta(i)) in the vicinity of both Co2+ impurities should be considered. The local angles theta(i) are obtained from the calculations and the results are discussed. (C) 2003 Elsevier B.V. All rights reserved. |
