光第2高調波でドメインをみる Observation of Ferroic Domains by Means of the Optical Second Harmonic Generation
The optical second harmonic generation can be applied to the observation of ferroic domains. In particular, ferroelectric 180° domain structures were successfully observed using a nonlinear microscope termed SHG microscope. The principle utilizes the phase difference of the second harmonic waves produced in domains with opposite polarizations and the interference effect was utilized to make the intensity contrast. Other applications to the J-aagre-gate in monomolecular films and antiferromagnetic domain structure are also possible using the SHG microscope.
