| Abstract: | Precision field shift studies of Bappl-8T using pulsed FM NMR/ON along hard directions (eg <100>54MnNi, <112>125SbFe and the easy axis (<111>54MnNi, <100>125SbFe) yield no measurable Knight shifts within the uncertainty allowed by current accuracy of the nuclear moments. This is in
striking contrast to earlier measurements with the same apparatus that yielded K=+1.5 (4)% for60CoFe.
The modulation frequency dependences of the pulsed FMNMR/ON signals are investigated for a variety of rf parameters and compared
with model predictions. |
