LATTICE ANISOTROPY IN ANTIFERROMAGNETIC CHROMIUM,

Abstract

Thermal expansion and magnetostriction measurements on single-Q, single crystal chromium give the lattice parameter ratios in the transverse spin-density-wave phase, through the spin-flip transition, and in the longitudinal spin-density-wave phase. The spin-flip transition is found to be accompanied by anisotropic discontinuities in length, resulting in a net volume dilatation of 0.0000014 with decreasing temperature. The Q direction is found to be the longest axis at 300 degrees K and to become the shortest axis below about 220 degrees K. (Author)
