Abstract
We consider a cubic lattice of small magnetic spheres imbedded in a type II superconductor. We compute the field distribution for one sphere and the interaction energy when the moments are aligned. It is pointed out that the dipolar field due to the nearest neighbors, in opposition to the normal situation, is nonzero in the superconducting state and induces then an antiferromagnetic ordering of the moments.
