The structural, optical, and magnetic properties of pristine and Co doped Manganese Tungstate (MnWO4) nanostructures prepared by precipitation process are investigated and reported here. The tetragonal structure of pure and Co doped MnWO4 compounds is shown by X-Ray Diffraction (XRD) studies. The Scherrer equation was used to compute the crystallite size of the particles. Fourier Transform Infrared (FTIR) spectroscopy was used to analyse the appearance of metal oxide vibrations (Pb, W, O, and Co). The creation of agglomerated nano flakes of pure and Co doped MnWO4 samples are confirmed by electron microscope pictures. optical spectra delivered the excellent optical absorption behaviour and calculated bandgap suggested that the interaction of dopants with host lattice. Magnetization investigations show that the paramagnetic character of the pure and Co doped compound and carrier generated exchange interactions. According to the findings, the tunability of magnetism in the MnWO4 system at room temperature in relation to dopant concentration leads to the material being used to fabricate magneto-optical and electrical devices.
