Incommensurable surface spin structures in MnO-type antiferromagnets
A theory for the phase stability of incommensurable spin structures on the /001/ surfaces of the rock-salt antiferromagnets is presented. It consists of classical spins and a simple Heisenberg Hamiltonian dependent on three exchange interactions: (a) a surface-only nearest-neighbor exchange; (b) a surface-second-layer nearest-neighbor exchange; and (c) an antiferromagnetic second-nearest-neighbor superexchange throughout the crystal. Incommensurable magnetic surface structures are proven to be the ground state for a wide range of the surface exchange parameters. 21 refs., 6 figs.
