Abstract: Nuclear resonance reflectivity from a [Dy$_{19}$Gd$_{19}]\times20$ superlattice has been measured utilizing the $25.652$ keV nuclear level of $^{161}$Dy. The measured time spectra of nuclear resonance reflectivity make it possible to reveal the variation of the hyperfine magnetic field B$_{\text{hf}}$ on dysprosium nuclei in the temperature range of $4$–$110$ K and to determine the relaxation time of the hyperfine field, using the decay speed-up of the excited state of $^{161}$Dy nuclei.
