Extended Data Fig. 3: Temperature dependence of S parameters and damping.

a, Temperature dependence of the microwave absorption spectrum (S11). b, Numerically calculated magnon intensity at 31.93 mT at T = 300 K. The calculation was performed for a magnetic disc with a diameter of 100 μm and a thickness of 1.6 μm, using the same material parameters as those used to obtain Fig. 5a–c. c, Magnetic field dependence of microwave absorption spectrum, d, Frequency dependence of microwave absorption spectrum up to 5 GHz, e, Temperature dependence of intrinsic Gilbert damping constant. All data were obtained from repeated measurements (n = 10) of the same sample under identical conditions. These measurements correspond to technical replicates. Error bars represent standard deviation (SD) of the data. Data are presented as mean ± SD.
