Spin–Spin Coupling: Three-Bond Coupling (Vicinal Coupling)01:22

Spin–Spin Coupling: Three-Bond Coupling (Vicinal Coupling)

1.1K
Vicinal or three-bond coupling is commonly observed between protons attached to adjacent carbons. Here, nuclear spin information is primarily transferred via electron spin interactions between adjacent C‑H bond orbitals. This generally favors the antiparallel arrangement of spins, so 3J values are usually positive.
The extent of coupling depends on the C‑C bond length, the two H‑C‑C angles, any electron-withdrawing substituents, and the dihedral angle between the...

Spin–Spin Coupling: Two-Bond Coupling (Geminal Coupling)

994
Two NMR-active nuclei bonded to a central atom can be involved in geminal or two-bond coupling. Geminal coupling is commonly seen between diastereotopic protons in chiral molecules and unsymmetrical alkenes, among others.
The central atom need not be NMR-active because its electrons are affected by the electron polarization of the spin-active atoms. However, spin information is transmitted less effectively than in one-bond coupling, and 2J values are usually weaker than 1J values. The energy of...

Atomic Nuclei: Nuclear Spin State Overview

921
NMR-active nuclei have energy levels called 'spin states' that are associated with the orientations of their nuclear magnetic moments. In the absence of a magnetic field, the nuclear magnetic moments are randomly oriented, and the spin states are degenerate. When an external magnetic field is applied, the spin states have only 2 + 1 orientations available to them. A proton with = ½ has two available orientations. Similarly, for a quadrupolar nucleus with a nuclear spin value of...

Area of Science:

  • Spintronics
  • Materials Science
  • Condensed Matter Physics

Background:

  • Spin injection, transport, and detection are vital for energy-efficient spin logic devices.
  • Interfacial conductance mismatch, spin dephasing, and inefficient spin-to-charge conversion hinder device efficiency.

Purpose of the Study:

  • To demonstrate a high spin readout efficiency using an all van der Waals heterostructure.
  • To explore the potential of van der Waals (vdW) heterostructures for spintronic applications.

Main Methods:

  • Fabrication of an all van der Waals heterostructure combining a ferromagnet (Fe3GeTe2) and a Weyl semimetal.
  • Measurement of nonlocal and local spin readout signals.

Main Results:

  • Achieved a nonlocal spin readout signal of 150 mΩ and a local spin readout signal of 7.8 Ω.
  • Demonstrated signal levels suitable for practical spintronic devices.
  • Attributed the enhanced signal to suppressed spin dephasing, long spin diffusion, and efficient charge-spin interconversion.
