We report an experimental study on
optical and magneto-optical properties of Ce
substituted yttrium iron garnet thin films
incorporating gold nanoparticles. Au
nanoparticles were formed by heating Au thin
film on cubic quartz and garnet substrate in
vacuum chamber and a Ce:YIG layer was
deposited on them by the aid of Pulsed laser
deposition method. A large enhancement of the
longitudinal Kerr effect was obtained in sample
with Au nanoparticles on quartz substrate and
the effect of substrate material on improving
optical and magneto-optical response of samples
were investigated.
