Synthesized sample were characterized with X-ray powder diffraction method (XRDP). electrone microscopy (SEM and TEM), vibrating sample magnetometry (VSM) and vibrational spectroscopy methods (FTIR and Raman). Mathematical analysis of nanoparticle morphology was also conducted, applying shape descriptors on segmented TEM sample images..
