Title:
Polarization Dependence of the Magnetic Fluctuations in {{Cr}} below ${T}_{N}$
Abstract:
We have investigated the magnetic excitations in single-Q, single-domain Cr below TN using polarization analysis of inelastically scattered neutrons for energy transfers up to 18 meV. The results show that the longitudinal (L) magnetic modes are enhanced below $\simeq$8meV with respect to the transverse (T) modes at low temperature. The latter are independent of the polarization with respect to the ordering vector Q$′\pm$ in the transverse spin-density-wave phase, i.e., they are isotropic. The L...    »
