Dr. R. Justin Joseyphus
Dr. R. Justin Joseyphus received his Ph.D in the area of nanocrystalline magnetic materials from University of Madras in the year 2005. He pursued his post-doctoral research in Tohoku University, Sendai, Japan till the year 2007. He joined the Department of Physics as faculty in September 2007. He has published more than 100 research articles in international journals, and a book on 57Fe Mossbauer Spectrometry. Investigating soft and hard magnetic materials, the most significant research work includes the synthesis of Fe using an instant polyol reduction process, which has opened opportunities to explore the magnetic properties of chemically synthesized Fe-based alloys and their applications. His current research interest is in the structure-property correlation of magnetic materials and their applications.
