Abstract

The non-f compound ThRu₂Si₂ has been studied as an isostructural nonmagnetic reference for URu₂Si₂ using nuclear magnetic resonance (NMR) measurement. The temperature dependences of Knight shifts measured by ²⁹Si-NMR and ⁹⁹Ru-NMR are independent of temperature. The results are consistent with data previously reported on the susceptibility. ¹⁰¹Ru-NQR frequency ¹⁰¹ ν _Q was also estimated from the ⁹⁹Ru-NMR measurement. ¹⁰¹ ν _Q of ThRu₂Si₂ is close to that of URu₂Si₂, especially at high temperatures, suggesting that U ions in URu₂Si₂ are in a nearly tetravalent state.
