Abstract
The values of the spin-hamiltonian parameters are reported for systems Fe3+:Ca3Sc2Ge3O12, Fe3+:Na3Sc2V3O12 and Mn2+:Na3Sc2V3O12. The values of the axial parameterD together with the values ofD compiled from literature are used in the discussion of the origin ofD. A close correlation ofD with the trigonal deformation of the octahedron of S-state ion indicates the importance of the covalency effects. On the other hand, it is shown thatD can be hardly understood on the basis of the relativistic model only.
