Abstract :
We realize and experimentally study magnetic field reversible serial quantum Hall arrays. Our devices consist of two Hall bars with rectangular or square geometry connected in series. We show that for such serial Hall arrays, the correct quantum Hall resistances is measured for both field orientations when current and voltage leads are exchanged under magnetic field reversal. Precision measurements of the i = 4 plateau for the two field configurations are presented.
