Description
An experimental study of the high mobility GaAs/AlGaAs system at large-$ν$ indicates several distinct phase relations between the oscillatory diagonal- and Hall- resistances, and suggests a new class of integral quantum Hall effect, which is characterized by "anti-phase" Hall- and diagonal- resistance oscillations.
