Research Abstract

560 GHz time-resolved high-frequency ESR was developed by using30 tesla pulsed magnet and THz light source. Moreover,inhomogeneous nano-space was studied by the magnetic field effect (MFE) probe. In mesoporous silica MCM-41, increases of micro-viscosity were observed by formation of partially clusterization of solvent. In the case of ionic liquids, inhomogeneous structure, which lifetimes were 20-120 ns,was generated in spite of a liquid.
