Popis: A complete solution is given of Luttinger and Tisza's method for finding an approximation to the ground state of a quantum-mechanical system of dipoles on a Bravais lattice, interacting through dipolar and exchange forces. The results are applied to cerium magnesium nitrate and a layered, antiferromagnetically ordered ground state is predicted for this crystal.
