Abstract
Using the energy bands which we have previously calculated for double hexagonal‐close‐packed neodymium and praseodymium, we have calculated the generalized susceptibilities, χ(q), along several directions in the ΓMLA plane of the Brillouin zone. The bands were calculated using the relativistic APW method and the procedures used in calculating the susceptibility were similar to those employed by Evenson and Liu for their work on the heavy rare‐earth metals. There are several relatively flat pieces of Fermi surface nearly parallel to the KMLH plane which nest into each other. This nesting produces a peak in the susceptibility curve along ΓM at approximately 0.13b1. This wavevector corresponds to the b‐axis periodicity of the magnetic ordering for these two elements determined by neutron diffraction measurements.This publication has 5 references indexed in Scilit:
