Asymmetry of the Hall Conductance Fluctuations in a Random Magnetic Field

Abstract

Transport in a two dimensional electron gas (2 DEG) experiencing a random magnetic field has lately attracted intensive attention, due in large part to its relevance to the properties of the half-filled Landau level. One of the interesting features of the system is the absence of any time-reversal symmetry which would, for example, preclude weak localization. The delocalization problem in a rendom magnetic field system has been studied. In this paper we report on measured fluctuations of the asymmetne part of the Hall conductance in small samples (2 x 2 micron x micron) with a dimpled 2 DEG.
