Abstract

The spin-lattice relaxation time, T₁, of ⁸Li has been measured in a number of liquid LiSn and LiSi alloys, both as a function of temperature and of applied magnetic field. The relaxation rate, 1/T₁, in liquid LiSn plotted as a function of concentration exhibits a minimum at about 28 at.% Sn. This is qualitatively explained in terms of electron charge transfer from Li to the less electropositive Sn. Varying the concentration and the temperature, deviations were observed from the relation ση{all equal to} constant (σ denotes the electrical conductivity and η the Korringa enhancement). In liquid LiSi, the spin lattice relaxation rate is a decreasing function of the Si concentration up to approximately 43 at.% Si.
