The numerical calculations performed by Respaud et al. showed that the magnetic anisotropy has no significant effect on magnetization if α coefficient values are less than 1–2 [52] and [53]. In Table 2, endosperm is seen that corresponding α values for our samples are between minimum 30.52 and maximum 135.15. Even the minimum value is much above the limit of 1–2. Therefore, the investigated MnxFe3−xO4 NPs are in a highly anisotropic region described by Respaud et al.
