Electron transport in the plane of a monoatomic metallic layer with non-zero magnetization is considered. The material is represented by a two-dimensional set of disordered potentials which also possess spins aligned along one axis but not necessarily oriented in one direction. Such a system can be treated as a two-component alloy. The effective cross-section for conduction electrons has been calculated. The total conductivity is obtained within two-current model.

The diffusive motion of quasi-two-dimensional electron gas through an ultra-thin system of disordered potentials is considered. In such system the Fermi sphere splits into a set of independent sheets due to the small thickness of the system. Each sheet can be seen as an electron sub-band. The electron transport goes through these sub-bands independently. The sum of electrical conductivities over these sub-bands determines the total current which is calculated for ultra-thin films of cesium. We also present the relation between our approach and Landauer formalism based on the notation of the transmission coefficient.

The aim of this report is to investigate electronic properties of a chain of atoms when its translational symmetry is broken by a topological disorder. The study uses the inverse participant ratio to obtain information on the localization of electrons in phase space.
