Investigating Fe-doped Ba_0.67Ni_0.33Mn_1−xFe_xO₃ (x = 0, 0.2) ceramics: insights into electrical and dielectric behaviors

This study investigates the characteristics of Ba0.67Ni0.33Mn1–xFexO3 perovskite under varying Fe doping levels at the Mn-site (x = 0, 0.2). X-ray diffraction confirm the material's consistent structure, with Fe3+ ions substituting Mn3+ ions while maintaining identical ionic radius.
