Photo-induced electric polarizability of Fe3O4 nanoparticles in weak optical fields
Using a developed co-precipitation method, we synthesized spherical Fe 3 O 4 nanoparticles with a wide nonlinear absorption band of visible radiation. Optical properties of the synthesized nanoparticles dispersed in an optically transparent copolymer of methyl methacrylate with styrene were studied...

Optical properties of the synthesized nanoparticles dispersed in an optically transparent copolymer of methyl methacrylate with styrene were studied by optical spectroscopy and z-scan techniques. We found that the electric polarizability of Fe

; λ = 442 and 561 nm) and reaches a value of 10

. The change in polarizability is induced by the intraband phototransition of charge carriers. This optical effect may be employed to improve the drug uptake properties of Fe
