This study proposes a single-molecule spintronic switch using cobaltocene. Its spin configurations control electron flow, enabling switching with a magnetic field.

Area of Science:

  • Molecular spintronics
  • Quantum transport phenomena

Background:

  • Development of molecular switches is crucial for next-generation electronics.
  • Cobaltocene's unique spin properties offer potential for spintronic applications.

Purpose of the Study:

  • To propose and theoretically investigate a single-molecule spintronic switch and spin valve.
  • To explore spin-dependent transport properties of a cobaltocene-based molecular junction.

Main Methods:

  • First-principles density functional theory calculations.
  • Non-equilibrium Green function (NEGF) method for transport calculations.
  • Modeling of a lead-molecule-lead junction with two cobaltocene moieties.

Main Results:

  • Antiparallel (singlet) cobaltocene spin configuration blocks electron transport near the Fermi energy.

  • Parallel (triplet) configuration allows significantly higher electrical current.
  • Switching behavior observed, dependent on the insulating spacer and external magnetic field.

    • Conclusions:

    • The proposed cobaltocene-based molecular junction functions as a switchable spin valve.
    • Moderate magnetic fields can control the spin states and thus the current.
    • This work lays the foundation for designing single-molecule spintronic devices.
