From: On demand laser-induced frequency tuning of coherent magnons in a nanometer-thick magnet at room temperature

Fig. 4

a Magnon frequency as a function of the magnetic field and pump fluence. The colored boxes isolate datasets, represented in (c). b Fluence dependence of the magnon frequency in correspondence of μ0Hext = 60 mT and μ0Hext = 200 mT. The dashed and continuous lines are guides to the eye. c Calculated frequency shift using Eqs. M1–M3 (see Methods) and experimentally observed frequencies as a function of the in-plane external field corresponding to values of the excitation fluence equal to 0.5 and 8 mJ/cm2. d Extracted frequencies as a function of the in-plane external field from simulations of laser-induced dynamics for fluences of 2 and 20 mJ/cm2.
