摘要：

Self-consistent electronic structure calculations for a magnetic dimer supported on a metal surface are performed on the basis of the microscopic Hamiltonian for itinerant electrons. The possibility of a noncollinear ground state in the absence of spin-orbit interaction and magnetic frustration is shown. The effective exchange interaction of moments is determined by the number of quasi-localized d-electrons per atom and, in general, is not described by the Heisenberg model.
