Magneto-optic properties of particulate layers

Restriction of electron mean free path in small metallic particles leads to a modification of the bulk optical and magneto-optic constants. The effect of this restriction and particle shape on the effective macroscopic values of
\bar{n}
and
\bar{Q}
for a particulate layer are considered. Values of saturation polar Kerr rotation and Faraday effect figure of merit are calculated for different volume concentrations of nickel particles in a quartz matrix.
