CaCu3Ti3MnO12 (CCTMO) ceramic has been successfully synthesized by the semi-wet route and sintered at 1223 K for 8 h, which is confirmed by XRD analysis to ensure CaCu3Ti3MnO12 (CCTMO) phase formation. The microstructure, phase-structure, and thermal behavior were examined by scanning electron microscopy (SEM), X-ray diffraction (XRD), and thermogravimetric analysis (TGA), respectively. After Mn-doping, the dielectric constant decreases from 104 to 102. The particle size as well as grain size measured by TEM and SEM techniques which were found to be 43.76 ± 10 nm and 1.46 μm, respectively. The route mean square and average roughness observed by atomic force microscope (AFM) analysis were 0.141 μm and 0.109 μm, respectively. The temperature-dependent ferromagnetic nature of CCTMO ceramic was confirmed by zero field cooled (ZFC), field cooled (FC), and M-H hysteresis curves. The investigated magnetic property of CCTMO confirmed paramagnetic behavior at 300 K and ferromagnetic behavior at 5 K. The dielectric constant (ɛr) increases when temperature increases, although dielectric constant and dielectric loss were observed 100 and 0.1, respectively.
