Outline of Final Research Achievements

We have developed a novel ESR spectroscopy method for examining chirality of spin assemblage systems. The static longitudinal magnetization can be detected with a conventional SQUID magnetometer where a circularly polarized (CP) microwave is introduced with a waveguide. The waveguide suitable for the detection of macroscopic magnetization under the static magnetic field and the CP field was designed on the basis of electromagnetic field simulations. For a standard sample of an achiral organic radical, ESR signals were observed under the irradiation of the CP microwave field.
