摘要：

It is shown that the spin Hamiltonian of the spin-spin interactions, written with the use of effective spinons defined on the two lowest doublets of magnetic ions with a partially frozen orbital moment, has a non-Heisenberg form. The Heisenberg contribution is represented by spin-spin terms containing three powers of ion spin projections and is anisotropic and comparable to the bilinear spin-spin interaction.
