Dr. Hashim Jabbar and Ameer F. Shamkhi published a paper entitled " Comparison of structural and magnetic properties of magnetite nanoparticles prepared by green synthesis and chemical co-precipitation methods" in the "Plasmonics", which is indexed in Scopus/Web of Science database. the study aims to the green synthesis resulted in the highest Ms (56.97 emu/g), and Hc (5.302 Oe), whereas the co-precipitation method resulted in Ms  of 15.706 emu/g, and Hc of 25.581 Oe. Moreover, the different Ms and Hc values of the two methods were due to differences in sizes, shapes and surface effects of the prepared Fe₃O₄ MNPs. In other words, the green method produced particles with spherical shapes and smaller sizes than those of the co-precipitation method with rod-like structure, which in turn led to considerably higher saturation magnetization or exchange interaction together with lower magnetic anisotropy
