摘要：

The dipole-dipole interaction is calculated for antiferromagnetic configurations found in the REBa2Cu3O7-delta compounds, as a function of the spacing between ab planes. Crossover from three-dimensional to two-dimensional behaviour is demonstrated for both the ground state energy and the coefficients of the quadratic terms in the propagator.
