Abstract
Quasi-two-dimensional transport is investigated in a system consisting of one ferromagnetic layer placed between two insulating layers. Using the mechanism of skew-scattering to describe the Extraordinary Hall Effect (EHE) and calculating the conductivity tensor, we compare the quasi- two-dimensional Hall resistance with the resistance of a massive sample. In this study a new mechanism of EHE (geometric mechanism of EHE) due to non-ideal interfaces and volume defects is also proposed.
