Rate My Professor Y Sundarayya

Professor Y. Sundarayya serves as Professor and Head of the Department of Physics in the School of Sciences at Nagaland University, Lumami Campus. The Department of Physics was established in 2013 and began offering M.Sc. (Physics) and Ph.D. programs from the academic year 2014-15, with research emphases in condensed matter physics, multiferroics, magnetism, spectroscopy, energy materials, luminescent materials, and ab initio methods. Professor Sundarayya's academic interests center on condensed matter physics, encompassing multiferroics, magnetism, spectroscopy, energy materials, and ab initio methods. His research involves the synthesis, structural characterization, and investigation of magnetic and ferroelectric properties of nanomaterials, including orthoferrites, perovskites, and battery materials like LiFePO4.

Professor Sundarayya has authored numerous peer-reviewed publications in prestigious journals, demonstrating significant contributions to the field. Key works include 'Spin-Reorientation, Ferroelectricity, and Magnetodielectric Effect in YFe1-xMnxO3 (0.1 ≤ x ≤ 0.40)' in Physical Review Letters (2011, 182 citations), 'Covalent modification and exfoliation of graphene oxide using ferrocene' in Nanoscale (2010, 131 citations), 'Interplay of 4f-3d magnetism and ferroelectricity in DyFeO3' in Europhysics Letters (2013, 77 citations), 'Structure and magnetic properties of the Al1−xGaxFeO3 family of oxides' in Journal of Solid State Chemistry (2011, 58 citations), and 'Oxalate based non-aqueous sol–gel synthesis of phase pure sub-micron LiFePO4' in Materials Research Bulletin (2007, 58 citations). Recent publications feature 'Temperature assisted size dependent synthesis and magnetic properties of rare-earth chromium oxide nanoparticles' in Journal of Magnetism and Magnetic Materials (2022, 9 citations), 'Isovalent substitution of vanadium in LiFePO4' in Inorganic Chemistry Communications (2023, 5 citations), and 'Surface ferromagnetism in Y2Sn2O7 pyrochlore nanoparticles' in Journal of Alloys and Compounds (2024, 2 citations). His body of work has amassed over 580 citations. As HoD, he has led departmental initiatives, including hosting the 15th Physics Academy of North-East (PANE) conference in 2025, a precursor event to the National Space Science Symposium 2026, and serving as Principal Investigator for funded projects. He has delivered outreach lectures, such as a science talk at Kendriya Vidyalaya Lumami, and contributed to Ph.D. admissions and research committees at the university.
