Quantum Interference Effects in Lithium Ring Arrays

Abstract
We report detailed measurements on the weak-localization corrections in well-defined and -characterized arrays of quasi one-dimensional normal-metal rings. The Bohm-Aharonov oscillations are very well resolved. Measurements on sets of samples of varying ring size and geometry determine the distinct effects of these parameters and allow an unambiguous, quantitative comparison to the weak localization theory for ring geometries.
