Abstract
We report on magnetoresistance transport measurements performed on a bipart ite tiling of rhombus in the: GaAs/GaAlAs system. We observe for the first time large amplitude h/e oscillations in this network as compared to the on e measured in square lattices of similar size. These oscillations are the s ignature of a recently predicted localization phenomenon induced by Aharono v-Bohm interferences in this peculiar network.
