Scientific Interest and Work
Applying extreme pressure to search for novel magnetic, superconducting, and other highly correlated electron behavior in various materials.
Pressure is an exceptional parameter to investigate new materials as it can tune the physical properties by changing the interatomic distances. Dr. Jinhyuk Lim’s current research interests are focused on the search for novel magnetic, superconducting, and other highly correlated electron behavior in diverse materials by applying extreme pressure. These studies utilize diamond anvil cell (DAC) measurements of micro-Raman spectroscopy, ac magnetic susceptibility using He as a hydrostatic pressure medium, and electrical resistivity to non-hydrostatic pressures as high as 1.6 Mbar at cryogenic temperatures.
Dr. Jinhyuk Lim’s Ph.D. research specialized in high pressure studies on magnetism and superconductivity of selected heavy lanthanides and their alloys, such as Gd, Tb, Dy and Y(Gd), Y(Tb), Y(Dy). The effect of high pressure on these materials is, in particular, interesting as their strong electron-electron correlations are dramatically altered as the interatomic distances decrease. Dr. Lim also had research experience in synchrotron spectroscopic and scattering measurement techniques at the Advanced Photon Source performing NFS, XANES, XMCD, and XRD studies.
