Table 3. Fit parameters obtained from analysis of the M(H).
Here Ms is the saturation magnetization while β, dv2, σ2, and μ2 denote the volume fraction, the diameter of mean volume, the dispersion parameter and the mean magnetic moment of the MNP of the second mode of the fitted bimodal lognormal distribution. M3 is the MPS-amplitude at 3rd harmonics.
