Abstract

The Z-scan technique is used to measure the nonlinear refractive index n 2 and the nonlinear absorption coefficient β of ionic magnetic colloids as a function of the nanoparticles’ diameter ( D r x ) in the femto- and millisecond time-scale regimes. A change from a convergent-lens type (at a femtosecond time scale) to a divergent-lens type behavior (at a millisecond time scale) is observed. From the values of n 2 and β measured in the femtosecond time-scale regime, the third-order susceptibility χ ( 3 ) is calculated and is shown to depend on D r x : the smaller the D r x , the bigger the χ ( 3 ) . A possible origin of the high values of χ ( 3 ) found may be confining effects related to the physical nanoscale of the magnetic particles.
