Fitting results of five parameters under different ball grinding times, showing (a) equivalent anisotropic field H_k varying with ball grinding time, (b) static magnetic susceptibility χ₀ varying with ball grinding time, (c) damping factor α varying with ball grinding time, (d) circular frequency of eigenvibration of domain wall ω_r and the circular frequency of relaxation frequency ω_τ varying with ball grinding time. The unit 1 Oe = 79.5775 A⋅m⁻¹.
