摘要：
We study small identical magnetic particles embedded in a non-magnetic medium with their centers lying in a two-dimensional regular lattice. Within the approximation of the Weiss molecular held due to the magnetic dipole moments of the neighboring particles on the spins of a central particle, we derive general expressions for magnetization and magnetic susceptibility of the system. As an application, we discuss the ordering for a square lattice. (C) 1999 Elsevier Science B.V. All rights reserved.
