Magnetic and Structural Properties of CuO and Mn/Fe-Doped CuO Nanosheets for Nanomagnetic Device Applications

In this study, CuO and Cu₀.₉₂Mn₀.₀₂Fe₀.₀₆O nanosheets were synthesized via the hydrothermal method. X-ray diffraction (XRD) was employed to characterize the structural features of the samples, while field-emission scanning electron microscopy (FESEM), elemental mapping (Map), and energy-dispersive X-ray spectroscopy (EDS) were used to investigate their surface morphology. The magnetic properties of the samples were examined using a vibrating sample magnetometer (VSM). The results of quantitative and qualitative analyses revealed that both samples grew in nanosheet form and exhibited a monoclinic structure with the C2/c space group. Magnetic measurements indicated that pure CuO exhibits paramagnetic behavior, whereas the Mn- and Fe-doped compound Cu₀.₉₂Mn₀.₀₂Fe₀.₀₆O demonstrates ferromagnetic properties.
