Figure 5. Figure 6. Effect of chemoselective dissolution induced-by different reaction mechanisms All of the aforementioned dissolution reactions were evaluated in terms of a spontaneous chemical reaction with a lower Gibbs free energy. Figure 7. Applicability of the chemoselective dissolution effect on other hard magnetic phases As mentioned previously, a near theoretical value of M s was a clear manifestation of a highly pure single-phase magnet as verified from XRD, TEM, and ICP-AES analysis. Table 1 Summary of the saturation magnetisation M s values of chemically synthesized rare earth-based magnetic nanomaterials with various treatment solutions in our study and other literature.
Conclusion In this study, we examined the magnetic properties of calcium-reduced Sm 2 Co 17 nanofibres prepared with various treatment solutions i. Preparation of calcium-reduced hard magnetic nanostructures As a hard magnetic material, Sm 2 Co 17 was comparatively easier to prepare than three-element systems such as Nd-Fe-B. Chemoselective dissolution procedure 0.
