Temperature dependence of FMR characteristics of Bi2Se3/YIG. a, b f vs. Hres data for various T for YIG(23) and Bi2Se3(25)/YIG(15), respectively. Solids lines are fitted curves using Eq. (2). c, d, e, and f T dependence of Hres, ΔH, 4πMeff, and Heff of one YIG(23) single layer and two Bi2Se3/YIG bilayer samples, Bi2Se3(25)/YIG(15) and Bi2Se3(16)/YIG(17), respectively. The arrows in c and d denote the position of the hump-like features. Solid lines are guides of the eyes obtained by properly smoothing the experimental data. The inset of e shows the T dependence of Hint. The dashed lines indicate the hump position shown in c and d
