Abstract
In liquid In0.83Te0.17 which exhibits demixing at Tc=835 K, we have measured the nuclear spin relaxation rate R of the isomeric probe 117msb by a TDPAD technique. Within an interval of 50 K, an increase of R by about 30% is observed as T → Tc. This phenomenon is interpreted as indicating a marked increase of concentration fluctuations over small regions in r-space.
