Dr. Man-Gui Han obtained his PhD degree in Materials Science and Engineering from Iowa State University (USA) in 2004. Currently, he is a professor in the University of Electronic Science and Technology of China. He is also one of the journal editors of IEEE Transaction on Magnetics starting from 2012. Up to now, he has published more than 70 peer-reviewed journals papers in the fields of magnetic materials with especial interests in the high frequency properties and applications of magnetic materials. One of his research interests is to employ the Mössbauer spectroscopy to study magnetic materials. He has established his academic reputation by finding a giant magnetostrictive effect in Gd5(Si0.5Ge0.5)4, developing electromagnetic wave absorption materials, and the realisation of negative imaginary parts of high frequency permeability by spin transfer torque effect. He has given several invited talks in the international conferences in Germany, Russia, United Kingdoms and China.
