Quasi-two-dimensional extraordinary Hall effect

Quasi-two-dimensional transport is investigated in a system consisting of a very thin 1 nm ferromagneticlayer sandwiched between two insulating layers. Using the mechanism of skew scattering to describe theextraordinary Hall effect EHE and calculating the conductivity tensor, we compare the quasi-two-dimensionalHall resistance with the Hall resistance of a massive sample. In this study, a mechanism of EHE geometricmechanism of EHE due to nonideal interfaces and volume defects is also proposed.
