Ensembles of iron nanocrystals embedded within a matrix of SiO2 were found to exhibit an ultrafast magnetic relaxation. One specimen in particular, containing nanocrystals ranging up to 20 nm in diameter, also exhibited giant Faraday rotation, with a Verdet constant a 7.9 +/- 0.5 deg/A (6.3 +/- 0.4 deg/cm/Oe) and a still-unsaturated Faraday rotation of 3.8 +/- 0.2 x 103 deg/mm. The dynamic response of the nanocrystals to a transient magnetic field produced by an ultrafast current pulse propagating through a lithographically patterned transmission wire was probed using time-resolved magneto-optical Kerr microscopy. The rise time of the magnetic response to a transient out-of-plane field was observed to be as fast as 26 ps. The response time was found to vary as a function of the magnitude of an in-plane bias field with the fastest rise-times observed for both zero bias field and the high bias fields (around 135 kA/m or 1.7 kOe). The results will be discussed in the context of complementary micromagnetics simulations. Magnetostatic interactions between nanoparticles are believed to play a significant role in determining both the static and dynamic properties of these nanocomposite materials.
