Manufacture of electrode used for e.g. capacitor, involves applying external magnetic field to magnetic material containing nitrogen and/or sulfur, magnetic graphene and magnetic graphite and controlling arrangement direction of molecules.

OOTA N

Light-element magnetic material used for e.g. recording media, comprises magnetic graphene in which chemical structure exhibiting magnetic asymmetry is provided to specific ends where graphene exists.

OOTA N, AWANO H

Organic magnetic material for e.g. electrode of lithium ion battery, contains magnetic graphene formed by subjecting edge portion of graphene to chemical modification to produce magnetic asymmetry between edge portions of graphene.

OOTA N, AWANO H

Meta-material used for optical components e.g. lenses and prisms, comprises unit elements in which at least one portion comprises graphene, and has negative refractive index.
