Abstract
In liquid Li-Bi, Li-Pb, Li-Sn and Li-Si alloys the spinlattice relaxation rate T1-1 of Β-active8Li (T1/2=0.8s) probe nuclei has been measured over wide concentration (c) and temperature (T) ranges. T1-1 is governed by hyperfine contact interaction with the conduction electrons. Near the compositions Li3Bi, Li4Pb, Li4Sn and Li4Si both (T1T)-1 and d(T1T)-1/dT versus c show marked extrema. These data, when combined with Knightshift and/or conductivity values, inform on the prolongation of the electron "residence time" and the reduction of the density of states at the Fermi surface. There is progressive tendency to electron localization and compound formation in the sequence Li4Pb, Li4Sn, Li3Bi with mainly ionic bonding in the case of liquid Li3Bi.
