我们对$\nu$=2双层量子Ha - 1体系中各种磁相及其之间的量子相变进行了精确的实验预测。特别地，我们分析了外部偏置电压对量子相图的影响，发现在输运和自旋极化测量中，有限偏置可以很容易地对最近预测的新型倾斜反铁磁相进行实验观察。
We make a number of precise experimental predictions for observing the various magnetic phases and the quantum phase transitions between them in the $\nu$=2 bilayer quantum Ha ll 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.
