Abstract

We study the phase diagram of the ν = 2 bilayer quantum Hall (QH) state. We measure the thermal activation energy elaborately as a function of the total electron density nT and the density difference between the two layers σ. At σ = 0, we clearly find three phases as increasing nT - the singlet phase, the canted antiferromagnetic phase and the ferromagnet phase. By making the similar measurements at σ = 0, we construct the phase diagram of the ν = 2 bilayer QH state in the σ - nT plane.
