Electron and Nuclear Spin Dynamics in Antiferromagnetic Molecular Rings

Open access
Meier, Florian, Loss, Daniel·2001·Physical Review Letters

Abstract

We study theoretically the spin dynamics of antiferromagnetic molecular rings, such as the ferric wheel Fe10. For a single nuclear or impurity spin coupled to one of the electron spins of the ring, we calculate nuclear and electronic spin correlation functions and show that nuclear magnetic resonance (NMR) and electron spin resonance (ESR) techniques can be used to detect coherent tunneling of the Néel vector in these rings. The location of the NMR/ESR resonances gives the tunnel splitting and its linewidth an upper bound on the decoherence rate of the electron spin dynamics. We illustrate the experimental feasibility of our proposal with estimates for Fe10 molecules.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • For large N, the maximum entanglement E scales as N^{-1/3} and is achieved at a time t0 linear in N.

    “Thus for any fi nite N , however large, the chain allows us to distribute entanglement of the order N -1 / 3 in a time t 0 linear in N .”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
