Theory of intrinsic Hall-like transport effects
Project goals
The project is devoted to study of intrinsic transport properties of selected systems. These properties are characterized by non-diagonal resistivity-tensor components which do not explicitly depend on energy dissipation in the current direction. Their determination will be based on an analysis of forces which are characteristic for the stationary state in finite-size samples. First, the aim is to determine the influence of the electron polarizability upon the Hall effect. Further, we want to establishthe system-boundary spin concentration, the characteristic feature of the spin Hall effect, in systems with spin-orbit interaction as a function of the applied current. To establish the degree, to which the anomalous Hall effect is an intrinsic phenomenon, a force analysis will be performed for ferromagnetic model systems.

Teorie intrinsických, Hallovu jevu podobných, transportních jevů
Annotation in Czech
Projekt je věnován studiu intrinsických transportních vlastností vybraných systémů. Jedná se o vlastnosti charakterizované nediagonálními složkami tenzoru odporu, které explicitně nezávisí na disipaci energie ve směru elektrického proudu. Jejich stanovení bude založeno na analýze sil charakterizujících stacionární stav ve vzorcích konečných rozměrů. Cílem je především stanovit vliv elektronové polarizovatelnosti na Hallův jev a dále určit koncentraci spinů na hranách systémů se spin-orbitální interakcív závislosti na aplikovaném proudu, která charakterizuje spinový Hallův jev. Pro ferromagnetické modelové systémy bude proveden rozbor sil s cílem stanovit, nakolik je anomální Hallův jev jevem intrinsickým.

Project results evaluation
Theoretical analysis of intrinsic Hall-like effects has been the main subject of the project. Except of the standard Hall effect induced by the external magnetic field attention has been devoted to the anomalous Hall effect observed on ferromagnetic materials and to the spin Hall effect in non-magnetic systems affected by the spin-orbit coupling. As a result the relation of these effects with ch
