Research Interest
Growth of superconducting thin films by a PLD (pulsed laser deposition) and a HPCVD (hybrid physical-chemical vapor deposition) techniques and study of physical properties for superconductors such as cuprates superconductors, Fe-based superconductors, and MgB2 superconductors. By using PPMS (physical property measurement system) and MPMS ( magnetic property measurement system), we investigate vortex dynamics in the mixed states in the wide temperature ranges of 2-300 K and the magnetic field ranges up to 9 Tesla.
