Abstract
(EN)
The present invention provides a composition comprising a plurality of magnetic nanocomposite particles. The magnetic nanocomposite particle comprises a magnetic metallic nanoparticle and a plurality of organic polymer ligands attached to its surface. The composition can also include a host matrix, such as a polymer, in which the magnetic nanocomposite particles are interspersed therein. The compositions of the invention have the Verdet constant of at least 5000 °/T-m.
