摘要：

Nuclear resonance reflectivity from a [Dy19Gd19] x 20 superlattice has been measured utilizing the 25.652 keV nuclear level of Dy-161. The measured time spectra of nuclear resonance reflectivity make it possible to reveal the variation of the hyperfine magnetic field B (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 Dy-161 nuclei.
