The structural, optical, and magnetic properties of pristine and Chromium (Cr) doped Manganese Tungstate (MnWO4) nanoflakes prepared by precipitation process are investigated and reported. The tetragonal structure of pure and Cr doped MnWO4 compounds is shown by X-Ray Diffraction (XRD) studies. The Scherrer equation was used to compute the crystallite size of the flakes. Fourier Transform Infrared (FTIR) spectroscopy was used to analyze the appearance of metal oxide vibrations (Pb, W, O, and Cr). The creation of a double taper-like structure in MnWO4 and the morphological alterations generated by Cr ions in the doped lead tungstate samples are confirmed by electron microscope pictures. Magnetization investigations show that the paramagnetic character of the pure compound and carrier generated exchange interactions, resulting in an anti-ferromagnetic phase transition in Cr doped MnWO4 samples with greater concentrations. 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.
