• The susceptibilities X(q) of heavy rare earth metals are calculated using the results of a linear muffin-tin orbital band structure method for the eigenvalues and eigenfunctions of each metal. The results of these calculations, including Gd, are very similar to those of yttrium. The variation of the susceptibilities with changes in the Fermi level is also investigated. The region of the Fermi surface called the "webbing" is thought to play a vital role in driving the exotic magnetic structures found in a number of the heavier rare earth metals. Our calculations don't show that the susceptibilities are very sensitive to the topology of the Fermi surface. It is argued that these results require an extension of conventional models of exchange interaction in heavy rare earth metals to include magnetic ordered band structure.
