Abstract

A nuclear quadrupole resonance (NQR) spectrum was used for observing 101Ru signals in small magnetic fields and Knight shift Kc was measured in the superconducting (SC) state. Kc 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.
