Slow oscillations of magnetoresistance in quasi-two-dimensional metals.
Slow oscillations of the interlayer magnetoresistance observed in the layered organic metal beta-(BEDT-TTF)(2)IBr(2) are shown to originate from the slight warping of its Fermi surface rather than from independent small cyclotron orbits. Unlike the usual Shubnikov-de Haas effect, these oscillations are not affected by the temperature smearing of the Fermi distribution and can therefore become d...
متن کاملStrongly Anisotropic Transport in Higher Two-Dimensional Landau Levels
Low-temperature, electronic transport in Landau levels N > 1 of a twodimensional electron system is strongly anisotropic. At half-filling of either spin level of each such Landau level the magnetoresistance either collapses to form a deep minimum or is peaked in a sharp maximum, depending on the in-plane current direction. Such anisotropies are absent in the N = 0 and N = 1 Landau level, which ...
متن کاملTemperature and Angular Dependence of the Magnetoresistance in Low Dimensional Organic Metals
Detailed studies of the magnetoresistance of α-(ET)2KHg(SCN)4 and α(ET)2TlHg(SCN)4 as a function of temperature, magnetic field strength, and field orientation are reported. Below 15 K, the temperature dependence of the magnetoresistance is metallic (dR/dT > 0) for magnetic field orientation corresponding to an angular dependent magnetoresistance oscillation (AMRO) minimum and nonmetallic (dR/d...
متن کاملStrongly Anisotropic Ballistic Magnetoresistance in Compact Three-Dimensional Semiconducting Nanoarchitectures.
We establish theoretically that in nonmagnetic semiconducting bilayer or multilayer thin film systems rolled up into compact quasi-one-dimensional nanoarchitectures, the ballistic magnetoresistance is very anisotropic: conductances depend strongly on the direction of an externally applied magnetic field. This phenomenon originates from the curved open geometry of rolled-up nanotubes, which lead...
متن کاملAngular dependence of the tunneling anisotropic magnetoresistance in magnetic tunnel junctions
Based on general symmetry considerations, we investigate how the dependence of the tunneling anisotropic magnetoresistance TAMR on the magnetization direction is determined by the specific form of the spin-orbit coupling field. By extending a phenomenological model, previously proposed for explaining the main trends of the TAMR in 001 ferromagnet/semiconductor/normal-metal magnetic tunnel junct...
