Abstract

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