Abstract
We make a number of precise experimental predictions for observing the various magnetic phases, and the quantum phase transitions between them, in the n [] 2 bilayered quantum Hall system. In particular, we analyze the effect of an external bias voltage on the quantum phase diagram, finding that a finite bias should readily enable the experimental observation of the recently predicted novel canted antiferromagnetic phase in transport and spin polarization measurements.
