Abstract

A nuclear quadrupole resonance (NQR) spectrum was used for observing ¹⁰¹Ru signals in small magnetic fields and Knight shift K_c was measured in the superconducting (SC) state. K_c was measured in the field range from 200 to 1200 Oe and at temperatures down to 80 mK, using nuclear-quadrupole-resonance spectra. It was found that ¹⁰¹K _c was invariant with respect to the field and temperature on passing through small critical field and transition temperature above 200 Oe. This indicates that the spin susceptibility along the c axis does not change in the SC state, at least, in the field greater than 200 Oe.
