โฆ Synopsis
We investigate the bilayer quantum Hall state at total Landau level filling factor n ยผ 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.

Hall and diagonal resistances of bilayer fractional quantum Hall systems are discussed theoretically. The bilayers have electrodes attached separately to each layer. They are assumed to be coupled weakly by interlayer tunneling, while the interlayer Coulomb interaction is negligibly small. It is sho
