About Bipul Deka

I am currently a PhD student under the supervision of Prof. Seenipandian Ravi and Prof. Alagarsami Perumal at Department of Physics, Indian Institute of Technology Guwahati.My thesis work focused on understanding the dielectric relaxations and the magnetic properties in Fe- and Ti- based perovskite oxides. The Fe-based perovskite oxides (BiFeO3, YFeO3) exhibit interesting magnetic properties, while the Ti-based perovskite oxides (PbTiO3, BaTiO3) are known for ferroelectricity. I was able to explore the interesting exchange bias, spin re-orientation phenomena and magnetodielectric coupling in YFeO3 by substituting Mn in Fe site .Iwas alsosuccessful to induce ferromagnetism in otherwise diamagnetic Ti-based perovskite oxides by substituting Ti by Fe. I have published part of my research works in peer-reviewed journal like Journal of Alloys and Compounds, Ceramics International, Physica B, Journal of Superconductivity and Novel Magnetismetc.
During the course of graduate studies, I have handled some sophisticated instruments like X-ray diffractometer (Rigaku, TTRAX III), Vibrating sample magnetometer, LCR meter, ESR spectrometer, UV-VIS-IR spectrometer and assembled furnace that works for high temperatures. I have the expertise in refinement of XRD patterns by Rietveld refinement technique using FULLPROF software. Moreover, I have extensively used CNLS program, several software like ZSimpWin, EIS Analyzer to study the dielectric dispersions.
