Abstract
AbstractMeasurements of the Knight shift of 115In and 71Ga in liquid InGa bulk samples are carried out as a function of temperature from 263 to 523 K and concentration from 0 to 100 at% Ga. It is shown that bulk and particle samples give, within the experimental error, the same Knight shift values. The results are compared with contradictory experimental data in the literature, and it is found that they agree with those of one of the earlier authors. A further important result based on these measurements extended over a broad temperature range is the determination of the temperature coefficient of the Knight shift of both isotopes 115In and 71Ga as a function of concentration. The 115In temperature coefficient decreases with increasing Ga concentration whereas the 71Ga one remains almost constant over the entire concentration range. Comparisons between the experimental and the theoretical results show satisfactory agreement in some cases but strong discrepancies in others.
