Abstract

We describe our resistively detected nuclear-spin relaxation measurements on bilayer electron systems in double quantum wells. The measurements were carried out to study the compressible-incompressible transition at total filling factor νtot = 1 and the canted antiferromagnetic order and its Goldstone mode predicted for νtot = 2. The data demonstrate how nuclear-spin relaxation can shed light on spin/pseudospin order and associated phase transitions that may not be visible through conventional transport or optical measurements.
