Abstract

We investigate the bilayer quantum Hall state at total Landau level filling factor ν = 1, which is the best system to study the pseudospin ferromagnetism, where pseudospin represents the layer degree of freedom. We found an anisotropic magnetoconductivity near the commensurate-incommensurate phase transition point, which is induced by an in-plane magnetic field. We attribute this anisotropy to the formation of a stripe-shaped domain structure of pseudospins called soliton lattice phase. We also discuss dissipation mechanism in terms of the thermodynamics of pseudospin solitons.
