Irradiation-induced confinement in a quasi-one-dimensional metal

Abstract

The anisotropic resistivity of PrBa${}_2$Cu${}_4$O${}_8$ has been measured as a function of electron irradiation fluence. Localization effects are observed for extremely small amounts of disorder corresponding to electron mean-free-paths of order 100 unit cells. Estimates of the localization corrections suggest that this anomalous localization threshold heralds a crossover to a ground state with pronounced one-dimensional character in which conduction electrons become confined to a small cluster of chains.
