Zero-field FMR of the Bi2Se3(25)/YIG(15) sample. a, b FMR first derivative and microwave absorption spectra for various T, respectively. The arrows indicate the Hext sweep direction. The dashed line in b traces the T evolution of the absorption peak Hpeak. c, d, and e Schematics of the Bi2Se3/YIG sample when T = 100, 25, and 5 K, respectively. f Zero-field FMR temperature T0 as a function of f
