摘要：
We have observed a pronounced change in the conductance of a high-mobility two-dimensional electron gas (2DEG) caused by additional scattering of electrons at magnetic flux tubes (vortices) which are formed at the 2DEG by a superconducting 'gate' layer. The experimental results are in good agreement with theory if account is taken of the small-angle nature of electron-vortex scattering.
