After completed his M.S. and Ph.D. degrees in Materials Science and Engineering at Stanford University in U.S.A. in 1999, Professor Jongill Hong worked at Fujitsu Limited in Japan to research and develop a GMR-based spintronic (magnetoelectronic) sensor for HDD applications. He took part in setting the world record in magnetic recording density over 100 Giga-bit/inch2 in 2001 at Fujitsu Limited.
Since 2002, Prof. Hong has served as a faculty member in the department of Materials Science and Engineering at Yonsei University in Seoul, Korea. His primary interest is with novel magnetic materials and devices. His current research thrust is to realize new spintronic devices composed of nano-sized magnetic ultra-thin film systems, such as magnetic superlattices, magnetic tunnel junctions and ferromagnetic graphene. Spin detection and manipulation in ultra-thin magnetic/non-magnetic multilayers and spin transistors are another main thrust in his group. Ferromagnetic graphene and spin circuits on graphene have also been intensively exploring in his group.
Professor Hong has published more than 50 peer-reviewed research articles as the first or the corresponding author in prestigious journals including Nature Nanotechnology, Nature Communications, ACS Nano and ACS Applied Materials and Interfaces. He received the Prime Minister’s Commendation for the excellency of research funded by Korean Government.
