Many liquids do not crystallize when temperature is lowered. Their viscosity goes up very fast and they freeze in a disordered solid, called glass. This phenomenon is still poorely understood. The glass transition scenario of dynamical heterogeneities supposes that molecules movements are correlated in clusters growing in size when temperature is lowered, as in a phase transition. This had never been measured in supercooled liquids. In order to measure these correlations, two methods were proposed, based on linear and non linear susceptibility measurements. We developed an experiment to measure the dielectric susceptibilies. Since the non linear signal is very small, an original experimental setup was specially developed. Our measurements s...
