Квантові ефекти небалістичного транспорту в плівках на основі сполук PbSnAgTe

Based on the theory of weak localization, taking into account the mechanism of spin-orbit scattering, thepatterns of change in the magnetic conductivity of films PbSnAgTe are considered. The dependences of themagnetoresistance of PbSnAgTe films in magnetic field perpendicular to the surface of the film are studied.It is shown that for polycrystalline films on mica-muscovite substrates, the time of spin-orbital interactiondepends on the composition and may change the sign of the magnetoresistance.
