Description

Nuclear resonant scattering of synchrotron radiation from the 25.6 keV level of 161Dy is studied with two techniques: nuclear forward scattering (NFS) and nuclear incoherent scattering (NIS). NFS time spectra of Dy metal are measured at temperatures ranging from 15 K to 80 K. They reveal electron spin relaxation in ferromagnetic dysprosium with long relaxation times of ≅10-30 ns. NIS energy spectra of Dy2O3 at room temperature are measured with meV resolution. Scattering accompanied by phonon excitation is observed. (orig.)
