    • The excitation field amplitudes in Refs. are 3 and 6 mT, respectively. In Ref., the field amplitude is not estimated. However, the core shift amplitude is small, which suggests that the field was within the linear regime.

    • In Ref., the frequency of excitation was 62.5 MHz. Additional data taken on Permalloy squares of the same size and thickness using our low-frequency excitation scheme show that the gyrotropic mode frequency is ∼35 MHz. Thus, the core trajectory should be elongated rather than circular; see 10.1103/PhysRevB.78.014405
