Abstract

The magneto-optical and opto-magnetic effects describe the interaction of light with a magnetic medium.The most prominent examples are the Faraday and Cotton-Mouton effects that modify the transmission of light through a medium, and the inverse Faraday and inverse Cotton-Mouton effects that produce effective magnetic fields for the spin in the material.Here, we introduce the phenomenology of the analogous magneto-phononic and phono-magnetic effects, in which vibrational quanta take the place of the light quanta.We show, using a combination of first-principles calculations and phenomenological modeling, that the effective magnetic fields exerted by the phonon analogs of the inverse Faraday and inverse Cotton-Mouton effects on the spins of antiferromagnetic nickel oxide yield magnitudes comparable to and potentially larger than those of the opto-magnetic originals.

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

  • A recent theoretical work found that in semimetals and small-gap (tens of millielectronvolts) insulators, a four orders of magnitude enhancement of the phonon magnetic moment can be expected.

    “A recent theoretical work29 found that in semimetals and small-gap (tens of millielectronvolts) insulators, a four orders of magnitude enhancement of the phonon magnetic moment can be expected30–32.”

    From Terahertz electric-field-driven dynamical multiferroicity in SrTiO3 (2024) · cites this paper as [31]

    The Discussion (page unavailable) mentions phonon excitation at energies of tens of meV and a possible application in small-band-gap semiconductors. It does not report a four-orders-of-magnitude enhancement of the phonon magnetic moment in semimetals or small-gap insulators. Searches for that magnitude and those material classes found no passage establishing the attributed finding. (LLM, conf=0.72)

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.
