“…For the typical sample with t = 500 nm, it is seen that is more than 110 below 1.0 GHz, while the imaginary part is much smaller than , which indicates that the film can be the potential materials applied on sensors operated in high frequency range. The increases to a maximum at f = 1.65 GHz, which can be ascribed to the ferromagnetic resonance FMR, the FMR frequency is stated as [11,18]:…”
