Frozen magnon theory and its application to commensurate antiferromagnetic chromium alloys
TLDR
In this paper, a new method is proposed for the calculation of the long wavelength part of the magnon dispersion curves of itinerant magnetic systems, which is the exact analog of the rigid muffin-tin approximation for the phonon frequencies in transition metals.About:

Electronic Structure of Chromium Group Metals
TL;DR: In this paper, the position of the Fermi surface of non-magnetic chromium was estimated based on electron energy levels in body-centred cubic transition metals, and it was shown that almost the whole of this surface is placed so that the introduction of an antiferromagnetic superlattice will lower the electron energy, so that such a structure should be expected to be stable at low temperatures.

Band Theoretical Interpretation of Neutron Diffraction Phenomena in Ferromagnetic Metals
TL;DR: In this paper, the correlation effect of electrons is taken into consideration by a ladder approximation, and the itinerant electron model is shown to be capable of accounting for the observed diffraction equally well.
