Introduction
The Faraday effect (magneto- optic effect (MO2)) is
more important specially in potential application
research such as optical sensors, optical isolators
and MO2 memory system (1–4). Faraday effect is
study the interaction between the intensity of the
light with the matter at presence the magnetic field,
(5–8) therefore the ferromagnetic (FM) nanoparticles
is interest. (9–13)
Materials and Methods
Poly Methyl Meta Acrylate (PMMA) doped with
TiO2 nanoparticles (size: 20- 30 nm, purity:
99.99%) manufacturer (Hongwu nanometer) is to
make solution molding mechanism. Mixture the
(PMMA/TiO2) by ratios (0.2, 0.4, 0.6 wt %) were
melted (30 ml) of chloroform using magnetic
stirrer, after that the samples dried.
A diode laser at wavelength of (540 nm) and spot of
a diameter of approximately (2mm). The radiation
is polarized along the propagation direction, the
beam pass through the cell (PMMA/TiO2). The film
is positional inside a coil has (B= 400 m T), when
the operation laser device the laser beam is filled
on the cell which is vertically to the wave vector. At
