POSTECH Professor Awarded James C. McGroddy Prize
04/14/2010 - Cheong Sang-wook, chair professor at Pohang University of Science and Technology (POSTECH), recently became the first Korean awardee of the James C. McGroddy Prize for New Materials. He was recognized for his contributions in advancing the understanding and utility of multiferroic oxides.
Cheong Sang-wook, chair professor at Pohang University of Science and Technology (POSTECH), recently became the first Korean awardee of the James C. McGroddy Prize for New Materials.
Sang-wook received the award along with Professor Nicola Spaldin of the University of California, Santa Barbara, and Professor Ramamoorthy Ramesh of the University of California, Berkeley, at a recent meeting of the American Physical Society (APS) in Portland.

Sang-wook is an expert of new material synthesis based on strongly correlated electron systems. He was recognized for his contributions in theory and experiments that have advanced the understanding and utility of multiferroic oxides.
The POSTECH professor offered a new paradigm in solid-state physics by demonstrating that a terbium manganese oxide (TbMn2O5) can control electric polarization, a slight relative shift of positive and negative electric charge in opposite directions within an insulator, or dielectric, induced by an external electric field. He recently published a joint-study paper in the February issue of Nature Materials that studied the ferroelectric domain structure of hexagonal YMnO3, a material of magnetic ferroelectrics, and its relationship with structural domains.
Sang-wook has published about 500 SCI papers since 1995, including seven in Nature and two in Science. POSTECH appointed him as chair professor of its physics department and accelerator laboratory in April 2006. Currently he is actively involved in a series of studies using a synchrotron, a particular type of cyclic particle accelerator in which the magnetic field and the electric field are carefully synchronized with a traveling particle beam.
The award, named after former IBM Senior Vice President and Special Advisor James C. McGroddy and endowed by the APS, is given to physicists with excellent achievements in the development and application of new materials. The award has been granted to 86 scientists since 1975.
