摘要：

We make a number of precise experimental predictions for observing the various magnetic phases, and the quantum phase transitions between them, in the v = 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 gin polarization measurements.
