Abstract

We report the observation of an anisotropic transport around a spin transition point in the Landau level filling factor ν = 2/3 in tilted magnetic fields. When a direction of the in-plane component of the magnetic fields (B) is normal to the current I, a strong hysteretic transport owning to the electron domain of different spin configurations emerges. When B is applied along I, the hysteresis almost disappears. At the same time, a current dependence of the anisotropy is examined. The hysteresis occurs by a nuclear-spin polarization which is generated when electrons pass across domain walls. Therefore the phenomenon suggests that a large number of electrons scatters by domain walls when B is perpendicular to I.
