We report on our studies of magnetic breakdown (MB) in coupled GaAs/Al 0.3 Ga 0.7 As double quantum wells (DQWs) subject to crossed magnetic fields. MB is a failure of semiclassical theory that occurs when a magnetic field causes electrons to tunnel across a gap in k-space from one Fermi surface (FS
