Abstract

Using Mössbauer spectroscopy, the magnetic properties of UPt3 have been investigated. The Mössbauer spectra in UPt3 shows that the paramagnetic hyperfine interaction is similar to that in UPd2Al3 and URu2Si2. The quadrupole interaction has been observed in the measured temperature range from 2.8 to 125K. Around Tχ max at which the magnetic susceptibility shows a maximum, the spectrum is the sharpest. Although the temperature dependence of the spectra in UPt3 is different from those in UPd2Al3 and URu2Si2, the obtained results suggest that the paramagnetic hyperfine interaction is related to the formation of the heavy fermion state in the 5f-electron system.
