Abstract	Measurements of the single top-quark production cross-sections with the ATLAS detector in pp collisions at the Large Hadron Collider (LHC) are presented. Results of measurements of single top-quark production in the t- and Wt-channel, as well as the determination of the CKM matrix element |V_tb| are shown. Further, the separate measurement of the top- and antitop-quark t-channel production cross-section and the ratio of the two are presented, and several searches for exotic processes in single top-quark production are discussed. The latter include results from searches for flavour changing neutral currents, extra heavy charged gauge bosons (W'), excited quarks, and searches for anomalous CP-violating couplings in the Wtb vertex.
