“…22 and 31, n Ag = 0.27+ 4.66i, n Au = 0.10+ 3.65i, and n Fe = 3.57+ 4.02i, and the linear MO coupling from Ref. 32, Q = 0.0437+ 0.0040i, is plotted as dotted lines. As found earlier by Qiu et al, 5 the material constants from literature approximately reproduce the Kerr ellipticity, which is insensitive to small phase changes of Q.…”

“…On the other hand, our value for the linear MO coupling Q for sample B is significantly by about 20% smaller and has a phase difference of about 17°compared to the data of Krinchik and Artemev. 32 The curve fitted to the data from the thinner sample departs from the experimental data at about 15 nm, which corresponds to approximately half the penetration depth of the light. This circumstance might hint at an improper description of the optical properties of the Ag substrate as a reason for the apparent thickness dependence of the index of refraction of Fe.…”

Magneto-optical ͑MO͒ Kerr effect ͑MOKE͒ magnetometry is one of the most widely employed techniques for the characterization of ferromagnetic thin-film samples. Some information, such as the magnitude of coercive fields or anisotropy strengths, can be readily obtained without any knowledge of the optical and MO properties of the material. On the other hand, a quantitative analysis, which requires precise knowledge of the material's index of refraction n and the MO-coupling constants K and G, is often desirable, for instance, for the comparison of samples which are different with respect to ferromagnetic layer thicknesses, substrates, or capping layers. While the values of the parameters n and the linear MO-coupling parameter K reported by different authors usually vary considerably, the relevant quadratic MO-coupling parameters G even for Fe are completely unknown. Here, we report on measurements of the thickness dependence ͑0-60 nm͒ of the linear and quadratic magneto-optical effects in epitaxial bcc-Fe͑001͒ wedge-type samples performed at a commonly used laser wavelength of 670 nm. By fitting the thickness dependence we are able to extract a complete set of parameters n, K, ͑G 11 − G 12 ͒, and G 44 for the quantitative description of the MOKE response of bcc-Fe͑001͒. We find the parameters n, K, and G to significantly differ for films thinner than about 10 nm as compared to those for thicker films, which is indicative of a thickness dependence of the electronic properties or of surface contributions to the MOKE. The magnitude of the quadratic magneto-optical effect is found to be about one-third of the record values reported recently for Co 2 FeSi.

“…It is well known that bismuth-substituted ferrite garnets (Bi:FGs) have a giant magnetooptical response [1][2][3][4][5][6][7][8][9]. For this reason, they have found widespread use as optical switchers, optical isolators and magnetic field sensors.…”

Faraday rotation and sensitivity of (100) bismuth-substituted ferrite garnet films

et al. 2002

We have investigated the Faraday rotation of in-plane magnetized bismuthsubstituted ferrite garnet films grown by liquid phase epitaxy on (100) oriented gadolinium gallium garnet substrates. The Faraday spectra were measured for photon energies between 1.7 -2.6 eV. To interprete the spectra, we use a model based on two electric dipole transitions, one tetrahedral and one octahedral. Furthermore, the Faraday rotation sensitivity was measured at 2.3 eV, and found to be in good agreement with the theoretical predicitions. In particular, we find that the sensitivity increases linearly with the bismuth content and nonlinearly with the gallium content.
