Abstract
The equivalence of averages calculated in canonical and microcanonical ensembles is shown to depend on the validity of a steepest-descent approximation. It is demonstrated that the microcanonical and canonical procedures yield different values for the order parameter below the Curie temperature for spherical model dipole lattices.Keywords
