Summary

Spin interactions in disordered electron systems affect transport properties. The difference in conductance between parallel and antiparallel magnetic contacts changes sign with channel length due to interference effects in two-component systems.

Area of Science:

  • Condensed Matter Physics
  • Spintronics
  • Mesoscopic Physics

Background:

  • Disordered two-dimensional electron systems (2DES) exhibit complex transport phenomena.
  • Ferromagnetic contacts introduce spin-dependent interactions influencing electron behavior.
  • Understanding spin-involved interactions is crucial for developing novel spintronic devices.

Purpose of the Study:

  • To investigate the impact of spin-involved interactions on the transport properties of 2DES.
  • To model the behavior of spin-up and spin-down electron components coupled at discrete points.
  • To analyze the influence of ferromagnetic contact magnetization orientation on conductance.

Main Methods:

  • Utilized a two-component model to describe the system.
  • Incorporated spin-involved interactions between spin-up and spin-down states.

  • Analyzed the interference effects arising in the two-component system.

    • Main Results:

    • The difference in conductance between parallel and antiparallel magnetic contact orientations was found to be sensitive to system parameters.
    • A sign change in the conductance difference was observed as a function of the conducting channel length.
    • This phenomenon is attributed to additional interference effects in the two-component model.

    Conclusions:

    • Spin-involved interactions significantly modify transport properties in disordered 2DES.
    • The observed sign change in conductance difference offers a tunable mechanism for spintronic applications.
    • The two-component model provides valuable insights into the interplay of spin, disorder, and geometry in electron transport.
