Abstract

In many multiferroic materials, the ferroelectric polarization is induced by a spatially varying magnetization such as a spin spiral. Here the authors introduce the reciprocal effect, in which a time-dependent electric polarization induces a magnetization even in previously nonmagnetic materials. The authors illustrate this dynamical multiferroic effect with four examples---the phonon Zeeman effect, the optical excitation of magnons and electromagnons, and the inverse Faraday effect---which they investigate using a combination of density functional theory, and microscopic and phenomenological analysis. The mechanism provides a general route to dynamically engineering new behaviors that are not accessible in the static domain.

  • Within a classical picture, the motion of ions in a closed loop induces an orbital magnetic moment of the order of the nuclear magneton μN ≈ 10−3 μB per unit cell.

    “Within a classical picture, the motion of ions in a closed loop induces an orbital magnetic moment, which is of the order of the nuclear magneton μN ≈ 10−3 μB per unit cell.”

    From Terahertz electric-field-driven dynamical multiferroicity in SrTiO3 (2024) · cites this paper as [7]

    Section III explains that circular ionic motion produces a magnetic moment summed over the ions in a unit cell. In “Resonant magnon excitation by optically driven phonons,” the paper reports a peak of about 0.1 μN per unit cell—described as the order of magnitude of a nuclear magneton—but this is for a simulated phonon excitation, not a general magnitude for any closed-loop ionic motion.

  • From symmetry considerations, the permutation of space and time and of electric and magnetic fields, a magnetization M is expected to appear in the presence of a time-dependent polarization.

    “On the other hand, from symmetry considerations, the permutation of space and time t, and of electric and magnetic fields, a magnetization M of the form is expected to appear in the presence of a time-dependent polarization7.”
  • From dynamical multiferroicity theory, one would expect the peak at ω+ to have negligible amplitude, whereas the experimental data show that the peaks are approximately equal.

    “However, from the dynamical multiferroicity theory7, one would expect the peak at ω+ to have negligible amplitude, whereas the experimental data show that they are approximately equal.”
  • In the original dynamical multiferroicity theory, no anharmonic effects were taken into account.

    “It is important to stress that in the original dynamical multiferroicity theory7, no anharmonic effects were taken into account.”
  • The frequencies of the two peaks in the difference signal are consistent with the prediction of dynamical multiferroicity, with a peak ω+ at twice the soft phonon frequency and one at ω− ≈ 0.

    “Their frequency is consistent with the prediction of dynamical multiferroicity7, with a peak ω+ at twice the soft phonon frequency and one at ω− ≈ 0.”

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.
