Abstract
In this work we study a set of related problems in the theory of ballistic spin transport. We draw special attention to the phenomenon of exchange coupling, which is interesting both from the theoretical point of view, and the possible applications in spintronics. For the calculations we employ the Landauer transfer matrix formalism, testing its assumptions, extending it to new models and establishing links with other branches of physics.
