Zusammenfassung

We investigate fluctuations in the magnetoconductance of noble-metal nanostructures in a mesoscopic two-lead configuration. The samples are gold and silver wires with lengths 500 and 1000 nm and widths w between 45 and 340 nm. The correlation field B_c varies as 1/w. Furthermore, the angle ? between the direction of the magnetic field and the current is changed continuously from 90°(usual geometry) to 0 °. The dependence of B_c on ? is weaker than B_c a B_c -/sin ?.
