Abstract: 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 field 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.
