Abstract

We investigate effects of an in-plane magnetic field B|| on the canted antiferromagnetic phase in the v = 2 bilayer quantum Hall (QH) state by the magnetotransport measurements under tilted magnetic fields. We elaborately measure the activation energy of the v = 2 bilayer QH state as a function of the total density nT for several tilting angles. We build up the phase diagram of the v = 2 bilayer QH state in the B|| - nT plane.
