title: Effect of magnetic dipole-dipole interactions on the spin orientation and magnetic ordering of the spin-ladder compound Sr3Fe2O5.
abstract: First-principles density functional theory calculations show that the spin-lattice of Sr(3)Fe(2)O(5) is practically 2D in terms of its spin-exchange interactions. The magnetic dipole-dipole interactions are found to be essential for the 3D magnetic ordering of Sr(3)Fe(2)O(5) at a very low temperature.
