A research team led by Dr. Youn-kyoung Baek and Dr. Jung-goo Lee succeeded in developing the world’s first technology to consecutively manufacture epsilon iron oxide that can absorb millimeter wave with a high coercive force equivalent to that of neodymium (Nd) magnets. The researchers are from the Department of Magnetic Materials in Powder Materials Division at the Korea Institute of Materials Science (KIMS), a research institute under the Ministry of Science and ICT.
