摘要：

Quasi-two-dimensional transport is investigated in a system consisting of a very thin (approximate to 1 nm) ferromagnetic layer sandwiched 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 Hall resistance of a massive sample. In this study, a mechanism of EHE (geometric mechanism of EHE) due to nonideal interfaces and volume defects is also proposed.
