Dr. Mumtaz research focuses on Material Science and Experimental Condensed Matter Physics, with a particular emphasis on multiferroic materials. Her work involves investigating these materials in various forms, including thin films, single crystals, and bulk ceramics. During her PhD, her research centered on pure and doped BiFeO₃, and now currently exploring composite multiferroics such as BaTiO3-CoFe2O4. She has prepared thin films using techniques such as spin coating using unique diol procrdure and pulsed laser deposition (PLD). She has developed comprehensive expertise in a wide range of experimental techniques aligned with her research interests. Her skills include X-ray diffraction (XRD), scanning electron microscopy (SEM), diffuse reflectance spectroscopy, and various transport measurements such as DC resistivity, AC impedance, and IV characterization. She is also proficient in low- and high-temperature dielectric measurements, as well as ferroelectric and magnetic property assessments, with a particular focus on exploring the interaction between ferroelectric and ferromagnetic behaviors. Additionally, she possesses hands-on experience working with polymers like PVDF, its copolymers, and their composites, further broadening her versatility in material research. |
