Abstract

The linewidth of the Ru nuclear quadrupole resonance (NQR) spectrum was measured in the superconducting state of Sr2RuO4 in order to search for the spontaneous field at the Ru site. We considered that the large hyperfine field would be expected at the Ru site in the superconducting state if the spontaneous field revealed by the μSR measurement originated from the nonzero spin moment. The linewidth of the spectrum is unchanged within an experimental error, which gives that the maximum value of the spontaneous field at the Ru nucleus site is less than 5 G if any. Our result suggests that the spontaneous field originates from the orbital component of the spin-triplet pairs.
