As shown in Fig. 25.14, the lackof direct correspondence between any Mossbauer component and the ferromagnetic component of the bulk ferromagnetism suggests that the latter in these garnets may arise not only from the rare doped magnetic iron ions but also from the crystal defects. While the MD/CF treatment increased the ferromagnetic moment in both samples, the magnetic sextets did not increase in the Mossbauer spectra in the case of x = 0.02, the sextets even shrink to their half.
