The11B and31P NMR Knight shift (K) and Korringa spin-lattice relaxation rate (1/T1T) have been measured for amorphous Ni81.5B18.5-xPx alloys with 0≤x≤18.5. In accordance with previous bulk measurements, the31P NMR parameters vary markedly with composition whereas the11B NMR parameters remain almost constant except for small P-contents. It is suggested that the d-band contribution to K(31P) is positive and that to K(11B) is negative. The data further support our previous conclusion that amorphous Ni81.5B18.5 is a Pauli paramagnet rather than a weak itinerant ferromagnet.
