Outline of Final Research Achievements

We investigated whether inverse Faraday effect, which is potentially utilized as a basis for optical control of magnetic properties of materials, can be enhanced with metal nanostructures. When a material is irradiated with circularly polarized light, which possesses twisted (spiral) field structure, the material is slightly magnetized (this phenomenon is called as inverse Faraday effect). However, this effect is usually very small. Because strongly twisted circular polarized field is sometimes induced when a metallic nanostructure is shined with light, we considered that inverse Faraday effect may be enhanced by the strongly twisted field with metallic nanostructures, and explored the possible utility for control of magnetic properties with light. Up to now, we have succeeded in observing circularly-polarized-light induced magnetization. We will continue the efforts toward characterizing properties of enhanced inverse Faraday effects by changing the sample materials and conditions.
