CONDUCTANCE FLUCTUATIONS IN MICROSTRUCTURES OF
... T = 4.2 K have shown the 2D character of the magnetoresistance for both cases. In contrast, the magnetoresistance measured on microcontacts at very low temperatures shows irregular fluctuations superimposed on the much less pronounced SdH oscillation pattern. Both the fluctuation amplitude and their ...
