Abstract
The electric quadrupole interaction of Mn-44 nuclei was studied in the weakly ferromagnetic system MnSi using muon level-crossing resonance (muLCR) technique. The temperature dependence of the electric field gr adient (EFG) shows a critical behavior near the ferromagnetic transiti on temperature, indicating that the EFG due to the conduction electron is strongly correlated with the magnetic susceptibility in the itiner ant electron magnetism. The temperature dependence of EFG is in reason able agreement with the self-consistent renormalization theory develop ed by Moriya and coworkers.
