Abstract
The present invention is produced by a composite with an Eu (II) compound nanoparticle and a metal nanoparticle. Such production generates quantum size effects of the Eu (II) compound nanoparticle, while the surface plasmon of the metal nanoparticle can be used. Thus, the magnetooptical property can be improved. In addition, a thin film may be produced by a composite with an Eu (II) compound nanoparticle and a metal nanoparticle.
