ResumoIn this research, Fe3O4 nanoparticles were synthesized and analyzed using scanning electron microscopy (SEM) and X-ray diffraction (XRD). The synthesized Fe3O4 with different compositional percentage doped in an E7 nematic liquid crystal (NLC). Nonlinearity of pure and doped NLC with Fe3O4 nanoparticles were studied by z-scan technique (close aperture and open aperture z-scan). The experimental results show that the nonlinear optical responses of Fe3O4 nanoparticles doped E7 can be changed by varying the compositional percentage of Fe3O4 nanoparticles. A small compositional percentage of Fe3O4 nanoparticles, 1% W/W, dispersing in a NLC showed improved nonlinearity.
