Enhanced magneto-optical rotation has been the
subject of intense interest for communication technology.
In this paper, we report an experimental study on the ef-
fect of Bragg reflector mirror and Au nanoparticles on the
magneto-optical rotation in a new magneto-optical structure
named magneto-plasmonic construction. Our results indi-
cate sufficient longitudinal magneto-optical Kerr effect en-
hancement in this new structure by the aid of combina-
tion of surface plasmon resonance and light localization in
magneto-optical garnet layer. The presence of Au nanopar-
ticles leads to screening of the surface plasmon resonance,
while Bragg reflector mirror reduces the group velocity in
magneto-optical medium as a defect layer and thus we have
sufficient enhancement in magneto-optical rotation. These
structures can be addressed as a new concept in the develop-
ment of magneto-plasmonic devices.
