| Abstract: | 57Fe Mössbauer spectra in external fields up to 13.5 T are recorded for two typical cluster glasses (Au, Fe) and Y(Fe, Al)2 to investigate the spin dynamics above the freezing temperature. The spectra are analyzed with a model in which magnetic clusters are assumed to form and decay stochastically. |
