Abstract
We have performed U-238 Mossbauer spectroscopy of uranium-based heavy fermi on superconductors, UPd2Al3 and URu2Si2, in order to investigate their phys ical properties, mainly their magnetic properties. The slow relaxation of m agnetic hyperfine interaction in a paramagnetic state and the static hyperf ine field has been observed in an antiferromagnetic ordered state for each compound. The line-widths have maximum at their characteristic temperatures where their magnetic susceptibilities have maximum values.
