Abstract

The spin-wave dispersion relations in the ferromagnet MnSb, and the antiferromagnet CrSb, have been measured, by neutron inelastic scattering, along high-symmetry directions in reciprocal space, as a function of temperature. The effect of composition is discussed. The dispersion in CrSb is found to rise very steeply as a function of q, and a gap in the excitation spectrum occurs at q = 0. The results for these itinerant electron magnetic materials are compared with previous experimental and theoretical work.
