“…The absolute values of the frequencies and the field dependencies are in very good agreement with the two modes of antiferromagnetic resonance in this compound [26,43,44]. Figure 2(d) shows how the Fourier amplitudes of the modes depend on the strength of the THz electric field.…”

“…If the THz pulse triggers spin dynamics, it can be translated in the dynamics of the magnetization. FeBO 3 has two modes of antiferromagnetic spin resonance: a low frequency quasiferromagnetic mode (q-FM) and a high frequency quasiantiferromagnetic mode (q-AFM) [43,44]. In spherical coordinates, where θ is the angle between L and the z axis, and ψ is the angle between the x axis and projection of L on the xy plane, one finds L ¼ 2jM 1;2 jðsin θ cos ψ; sin θ sin ψ; cos θÞ.…”

“…At RT, the magnon frequency was determined in [4] between 25 GHz and 64 GHz depending on the sample orientation, without external magnetic field. The optical antiferromagnetic mode was measured to be ~0.3 THz in an external field of 0.1 T at RT [5]. However, to the best of our knowledge, there is no measurement reported in the literature of dynamically resolved measurements of the relaxation following the excitation close to the magnon frequency.…”

“…2(d)) displays a decrease of some frequencies with an increase of the external magnetic field. The frequencies between 0.3 THz and 0.35 THz are of particular interest: according to [5] and the extrapolation of the data of [8] to room temperature, the anti-ferromagnetic mode is located between these frequencies. This mode has then been excited with the single-cycle THz pulse.…”
