摘要：

We have performed Si-29 NMR and Ru-101 NQR measurements on a single crystalline URu2Si2. From the Si-29 NMR measurements, any appreciable internal field at Si site was not observed in the antiferromagnetic state, indicating that tiny magnetic moments of U are not static but fluctuating faster than the NMR frequency. From the Ru-101 NQR line which is much narrower than that of polycrystalline powder, the electric quadrupole interaction parameter (va) was precisely evaluated to be 5.713 MHz at 4.2 K.
