Fig. 5.5 ia MOKE spectra of thin films consisting of 8, 10, and 12 nm size Co particles deposited on
Al substrate. b Co thin film reference spectrum. c Influence of solution dilution of the particles on the
MOKE signal [208] (Reprinted from [208], with the permission of AIP Publishing). iia Normalized
Faraday rotation spectra of γ-Fe 2 O 3 and Fe 3 O 4 nanoparticles. b Normalized Faraday rotation
spectra of γ-Fe 2 O 3 nanoparticles, gold-coated γ-Fe 2 O 3 nanoparticles, and a mixture of γ-Fe 2 O 3
and gold nanoparticles. The absorbance spectrum showing the plasmon resonance band of the
gold-coated γ-Fe 2 O 3 nanoparticles is indicated by the dotted blue curve [222] (Reprinted with
permission from [222], Copyright 2009 American Chemical Society). iii Comparison between
MCD magnetization curves for magnetite nanocrystal monolayers with and without a rough gold
film measured in transmission (a) and reflection (b) configurations [217] (Reprinted with permission
from [217], Copyright 2002 American Chemical Society). iv Optical absorption spectrum (red ◯),
and MCD (black ◯) of the gold nanoparticles. Optical absorption (A) is given in normalized units
at peak maximum (A/A Max ); dichroism (A) is scaled in accordance (A/A Max ) [229] (Reprinted
