Abstract

Nuclear-spin-relaxation time T1 has been measured in a balanced bilayer across the phase boundary between the correlated quantum Hall (QH) and uncorrelated compressible states at total Landau level filling factor v = 1. The measured T1, which probes electron-spin fluctuation, gradually decreases with decreasing the stability of the QH state. The gradual change indicates that the phase transition is continuous.
