Novel melting transition in a two-dimensional stripe-domain system

View publication

Abstract

The melting transition of the two-dimensional stripe-domain phase of bromine layers intercalated into graphite has been investigated by high-resolution x-ray diffraction. The transition is characterized by the progressive vanishing of successive harmonics so that near melting the density is described by a two-dimensional sine wave. Surprisingly, the sine-wave order parameter is best characterized by the power-law form, &, with 1 evolving continuously from 0.04 to 2.0 through melting. © 1987 The American Physical Society.
