Outline of Final Research Achievements |
In this research, we created room temperature artificial multiferroic materials by controlling a nano-space smaller than the wavelength of light, and examined a novel nonlinear optical effects. As a result, we found that by introducing artificial noncentrosymmetric nanostructures into conventional room temperature ferromagnets, ultrafast zero-bias photocurrents (spin-polarized photocurrents) were generated by the irradiation of fs laser beam. In addition, we found novel principles for light wavelength conversion and solar cell by inversion-broken spin arrangements.
