Previously unknown electric-field (current-) induced phase transitions into highly conducting states have been found in the solid phase of sodium–ammonia solutions at temperatures of 77 and 4.2 K. These states, in contrast to the starting states, are thermodynamically stable, both in the presence of the current and in its absence, up to the melting temperature of the eutectic, and are realized only in macroscopically nonuniform states, arising as a result of diffusion decomposition of the system at temperatures above 60 K. The resistance of the highly conducting phase is inversely proportional to the flowing current, up to the critical current.
