Query: The influence of the long-lived quantum Hall potential on the
  characteristics of quantum devices   Novel hysteretic effects are reported in magneto-transport experiments on
lateral quantum devices. The effects are characterized by two vastly different
relaxation times (minutes and days). It is shown that the observed phenomena
are related to long-lived eddy currents. This is confirmed by torsion-balance
magnetometry measurements of the same 2-dimensional electron gas (2DEG)
material. These observations show that the induced quantum Hall potential at
the edges of the 2DEG reservoirs influences transport through the devices, and
have important consequences for the magneto-transport of all lateral quantum
devices.
