In the present research we measured nonlinear refractive index of Fe3O4 nanoparticles using a single beam z-scan technique to compare with the results of far field diffraction. In both experiment we used a He-Ne CW laser beam operated at 632.8 nm to obtain nonlinear refractive index of Fe3O4 nanoparticles. %> http://opsi.ir/article-1-738-en.pdf %P 877-880 %& 877 %! %9 Research %L A-10-1-718 %+ %G eng %@ 1126-3278 %[ 2015
