Abstract
The magnetic hyperfine splitting frequencies of (NbNi)-Nb-90 and (MoNi )-Mo-93m in an external magnetic field of 0.2 T have been determined b y the NMR-ON method to be 18.52(7) and 23.73(10) MHz, respectively. Wi th the assumption of Knight shift factor K = 0 and with the known g-fa ctors, the hyperfine fields of (NbNi)-Nb-90 and (MoNi)-Mo-93m were ded uced as B(HF)((NbNi)-Nb-90) = -4.118(16) T and B(HF)((MoNi)-Mo-93m) = -3.491(33) T. The rather long spin-lattice relaxation time of 32(5) mi n was observed for (NbNi)-Nb-90 at an external magnetic field of 0.2 T and 8 mK.
