In this work we present a new concept for measuring high intensity pulsed magnetic fields (h (t)) through the spectral analysis of spin excitations in a saturated yttrium-iron garnet (YIG) thin film grown on a gadolinium gallium garnet (GGG) substrate. The spectrum of spin excitations, generated in the sample by picosecond h (t), was determined with the help of a magnetooptical (MO) Faraday probe in the guided wave regime of lightwave propagation. This technique, compared to the standard MO cells, allows one to avoid saturation effects because the amplitude of h (t) is measured in the frequency domain, and allows us to realize the analysis in real time taking advantage of strong a MO signal.

AbstractA novel single-source MOCVD technique was used to deposit Ce:YIG ((Ce,Y)3Fe5O12) films which were investigated for integrated magneto-optical applications, such as waveguide isolators. These films were grown on gadolinium gallium garnet substrates in order to optimize the growth conditions before growth on semiconductor substrates was attempted. We were able to achieve very high ratios of Ce:Y (= 0.4) due to the nonequilibrium nature of MOCVD. Ce:YIG films on GGG substrates were epitaxial with excellent optical and magnetic properties, along with high Faraday rotations that were comparable to commercial Bi:YIG. Planar waveguiding was observed in Ce:YIG films on both GGG and MgO substrates. MgO also proved to be a successful buffer layer for protecting the semiconductor substrates during YIG deposition. The Ce:YIG films on MgO-buffered GaAs had very promising magnetic properties, but the MgO deposition on InP must be optimized before successful Ce:YIG films on InP can be achieved.
