Anomalous low-field classical magnetoresistance in two dimensions.
نویسندگان
چکیده
The magnetoresistance of classical two-dimensional electrons scattered by randomly distributed impurities is investigated by numerical simulation. At low magnetic fields, we find for the first time a negative magnetoresistance proportional to |B|. This unexpected behavior is shown to be due to a memory effect specific for backscattering events, which was not considered previously.

Single phase polycrystalline Gd1-xPrxBa2Cu3O7-δ samples with x=0.05 , 0.10, and 0.15 have been prepared by standard solid state reaction technique and characterized by XRD and SEM analysis. The electrical resistivity, Hall effect and magnetoresistance measurements have been on the samples. The electrical resistivity measurements indicate a reduction of transition temperature (Tc) and an incre...
متن کاملMemory Effects in Backscattering of Two-Dimensional Electrons in Corrugated Systems
The classical low-field magnetoresistance (MR) in metals and semiconductors has been recently revised, since it was recognized that the conventional Boltzmann-Drude approach fails to describe the electron dynamics in disordered systems [1–3]. According to the Boltzmann-Drude model, magnetoresistance must yield no change, in the presence of short range electrostatic potential, which is in disagr...

We report direct observations of anomalous magnetic-field and temperature dependences of the Shubnikov–de Haas oscillations in the organic superconductor b9-(BEDT-TTF)2SF5CH2CF2SO3. Unlike other BEDT-TTF based organic superconductors, a nonmetallic temperature dependence of the background magnetoresistance is clearly observed. It is speculated that the nonmetallic behavior may arise from a part...
متن کاملSpin-Transfer Torques Generated by the Anomalous Hall Effect and Anisotropic Magnetoresistance
Spin-orbit coupling in ferromagnets gives rise to the anomalous Hall effect and the anisotropic magnetoresistance, both of which can be used to create spin-transfer torques in a similar manner as the spin Hall effect. In this paper, we show how these effects can be used to reliably switch perpendicularly magnetized layers and to move domain walls. A drift-diffusion treatment of the anomalous Ha...

Novel electromc properties of Iow-dimensional organic conductors.under high magnetic fields are briefly reviewed and some topical problems are discussed. Magnetic field effects to electron spins and electron orbital motions are discussed in the quasi one-dimensional conductors (RIR2DCNQI)2Cu and (TMTSF)2X and in the quasi two-dimensional conductor (BEDT-TTF)2XHg(SCN)4. Electronic properties in ...
