Abstract
The properties of a large number of individual steps in the conductanc e of atom-size contacts as a function of cross-section have been inves tigated. The results confirm that the steps are the result of atomic s tructural rearrangements, without exception for all individual steps i n the survey. Furthermore, we report the first direct observation of t he transformation of a hysteresis cycle around a conductance step in a two-level fluctuation. (C) 1998 Elsevier Science B.V.
