Abstract
We investigate fluctuations in the magnetoconductance (measured at mK) of noble-metal nanowires in a mesoscopic two-lead configuration, with lengths 500 and 1000 nm and widths between 45 and 360 nm. We determine the dependence of the correlation field on the angle between the direction of the magnetic field and the long axis of the wires. is changed at low continuously from 90° (usual geometry) to 0°. We present a calculation taking into account the 3D diffusive motion of the conduction electrons describing the angular dependence of . We compare this dependence with conductance fluctuations observed while sweeping at constant magnetic field.
