  Magneto-transport properties are investigated in a binary alloy ring
subjected to an Aharonov-Bohm (AB) flux \phi within a single-band
non-interacting tight-binding framework. In the first part, we expose
analytically the behavior of persistent current in an isolated ordered binary
alloy ring as functions of electron concentration N_e and AB flux \phi. While,
in the second part of the article, we discuss electron transport properties
through a binary alloy ring attached to two semi-infinite one-dimensional
metallic electrodes. The effect of impurities is also analyzed. From our study
we propose that under suitable choices of the parameter values the system can
act as a p-type or an n-type semiconductor.
