Abstract

Electrodeless Hall mobility measurements at the metal-non-metal (M-NM) transition in metal-ammonia (M-NH₃) solutions are presented. The possibility of electrode effects has been eliminated. These data corroborate previous conventional four-probe data which showed an excess mobility in Na-NH3 solutions near the composition corresponding to phase separation. The possible role of fluctuations on the M-NM transition is discussed in connection with the competing theories of Mott (1974) and Jortner and Cohen (1975). Data from a Li-Na-NH₃ alloy indicates a non-linear decrease in Hall mobility with decreasing Na/Li ratio.
