Abstract :
We measured the magnetoresistance in bilayer quantum Hall (QH) state at fractional filling factor View the MathML source. Surprisingly, for different QH areas and two types of hysteresis were observed by controlling the total electron density and the density difference in two layers. Two QH areas and one type of hysteresis are novel characteristic of bilayer systems.
