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 T_{χ 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.
