| Popis: | This paper reports the role of bioactive elements in inducing ferromagnetism in CdO nanopowder. CdO nanopowder was synthesized by a soft chemical method using aloe vera gel extract as solvent. XRD studies confirm the presence of diffraction peaks related to cubic crystal structure of CdO. Weak peaks related to the oxides of Cu, Fe, Mg, Zn, Ni and Mn were also observed. Nanosized grains were observed from the TEM image. EDX and XPS spectra confirm the presence of bioactive magnetic elements in the synthesized sample. Magnetic studies confirm that the paramagnetic nature of CdO becomes ferromagnetic due to the presence of magnetic ions in the aloe vera gel extract. |
