This paper describes the TE-TM mode conversion in a magneto-optical layer made by a SiO2/ZrO2 layer doped with magnetic CoFe2O4 nanoparticles. The mode conversion is caused by the Faraday rotation if the magnetization is aligned along the z-axis, parallel to mode propagation. The properties of this phenomenon are simulated using the full-vectorial beam propagation method (BPM). The simulation results show clearly the inuence of two parameters in such devices, the rst one is the o-diagonal component of tensor that enhances the rotation and the second one, the imaginary diagonal tensor (parameters K ) which makes it suering from absorption. This result of simulation is an important step to achieve a monolithic integration of optical isolators.

“…Magneto-optic Kerr spectra for iron containing spinels and garnets have similar transition structures for photon energies greater than 3 eV, [14][15][16] and therefore studies have focused on the polar Kerr rotation spectra below 3 eV. 3,13 In the present work, we studied the polar Kerr rotations for gallium substituted cobalt ferrite samples, CoFe 2−x Ga x O 4 with x = 0.4 and x = 0.8.…”

Long-lived, room-temperature electron spin coherence in colloidal CdS quantum dots Appl. Phys. Lett. 100, 122406 (2012) Resonant surface magnetoplasmons in two-dimensional magnetoplasmonic crystals excited in Faraday configuration J. Appl. Phys. 111, 07A946 (2012) Research on cobalt ferrite based composites has increased recently due to their potential applications such as noncontact magnetoelastic stress or torque sensors and erasable magneto-optic recording media. We report a study of the polar Kerr rotation spectra for CoFe 2−x Ga x O 4 ͑with x = 0.4 and x = 0.8͒. Each of the spectra consists of two peaks of negative Kerr rotation in the measured photon energy range of 1.5-3.0 eV. For x = 0.4, one peak occured at 1.8 eV and the other at 2.25 eV. For x = 0.8, the first peak shifted to a higher energy of about 1.9 eV, while the second peak remained at 2.25 eV. The origin of the peaks in the polar Kerr spectra and the observed shift of peak position resulting from Ga substitution can be explained by the intervalence charge-transfer transition, in which an electron from a metallic cation is transferred to a neighboring cation through an optical excitation.

“…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

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.
