Abstract
Far-infrared transmittance spectra of Mn1-xZnxF2 have been obtained at 1.2K in the frequency region from 3-15 cm-1 for x values from 0 to 0.49. The antiferromagnetic resonance frequency is observed to drop nearly linearly from the 8.7 cm-1 value for MnF2 to 4.0 cm-1 at 40% ZnF2. The linewidth broadened from <-1 to approximately 2 cm-1. Resonance frequencies obtained are compared with those from recent neutron scattering measurements.Keywords
