Monolithic Magneto-Optical Nanocomposites of Barium Hexaferrite Platelets in PMMA.

The incorporation of magnetic barium hexaferrite nanoparticles in a transparent polymer matrix of poly(methyl methacrylate) (PMMA) is reported for the first time. The barium hexaferrite nanoplatelets doped with Sc(3+), i.e.
