SUSCEPTIBILITIES USING FIRST-PRINCIPLES BAND STRUCTURES .2.

We have completed a program for the parallel calculation of the fully interacting static susceptibility from first principles LMTO band stru ctures using methods and programs developed in previous papers. We pre sent the results for the many-body enhanced static magnetic susceptibi lity chi(q) for Pd and FCC gamma-Mn and discuss how the simple Stoner criterion and its extension can give an incorrect physical picture of magnetic instabilities. We discuss the important local field effects w hich necessarily arise from an ah initio calculation of chi and give a more detailed discussion of the antiferromagnetic instabilities in FC C gamma-Mn.
