Exp 31 P NMR Measurements on Rapidly Quenched (Nisub(1-X)Cusub(X))sub(80)Psub(20) Metallic Glasses

摘要

The exp 31 P nuclear magnetic resonance was studied at room temperature as a function of the Ni/Cu ratio in rapidly quenched (Nisub(1-x)Cusub(x))sub(80)Psub(20) (0<=x<=0.77) amorphous alloys. The measured field-independent second moments agree with the results of earlier model calculations on dipolar broadening. The P-P dipolar interaction was found to be independent of the Cu content. Some data on Knight shift and spin-lattice relaxation time are also given and discussed briefly. (Atomindex citation 12:586466)
