Abstract

The magneto-optical response of nanometric Fe particles with varying size and shape has been studied, both in sputtered single layers and pulsed laser deposited nanocomposite films. The shape of Fe nanoparticles was controlled by varying growth conditions. An effective medium theory for arbitrary particle shapes has been derived and used to simulate the experimentally measured magneto-optical transverse Kerr spectra. The simulations show that the transverse Kerr magneto-optical spectra depend on the particles shape and correlate well with the experimentally determined spectra. From this result, it is deduced that Fe nanoparticles with dimensions down to 3-4 nm keep their bulk magneto-optical constants. On the other hand, large magneto-optical signals are reported in multilayered structures due to interferential effects.
