Research Focus & Scientific Contributions
Dr. Rao’s research spans experimental condensed matter physics and materials science, with emphasis on:
- Ferrimagnetic and spinel ferrite systems: investigating electrical transport, dielectric and magnetic properties of substituted ferrites such as Ni-Zn, Co-Mn and Mg-Mn ferrites, which are key for sensors and high-frequency applications. (ScienceDirect)
- Multiferroic and oxide nanocomposite materials: contributions to understanding structural, magnetic, and magnetoelectric interplay in composites like BiFeO₃-based systems. (ScienceDirect)
- Magnetostrictive and magnetoelectric effects: studies on magnetostrictive cobalt ferrite and doped multiferroic systems which are relevant to actuator and sensor technologies. (ResearchGate)
- Nanoparticle and core-shell composite formation: early work on Fe₃O₄/TiO₂ core/shell nanocubes for catalytic or functional applications. (ResearchGate)
- Magnetic thin films and layered structures: several collaborative works on exchange coupling, planar Hall resistance sensors, and microwave permeability in ferromagnetic/antiferromagnetic layers. (ResearchGate)
These investigations combine materials synthesis (sol-gel, ceramic, sputtering), structural characterization (XRD, Rietveld analysis) and magnetic measurements (VSM, Mössbauer, magnetotransport) to elucidate composition–structure–property relationships in functional magnetic systems.
