FARADAY EFFECT IN Ir-SUBSTITUTED MAGNETIC GARNET

Fe b 20 02 Faraday rotation and sensitivity of ( 100 ) bismuth - substituted ferrite garnet films

We have investigated the Faraday rotation of in-plane magnetized bismuth-substituted 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...

Temperature and high magnetic field dependence of the Faraday rotation in the terbium iron garnet

The Faraday rotation of terbium iron garnet at 1.15 03BC wavelength is presented. The experimental results have been obtained along the [111] easy direction both in low d.c. field 20 kOe as a function of temperature between 4.2 and 300 K and at room temperature as a function of the applied field (up to 1 200 kOe). The results are analysed in terms of magnetic and electric dipole contributions f...

Anisotropy of Ruthenium-substituted Yttrium-iron-garnet

Exploiting MO Crystals and Faraday Effect in Magnetic Sensing

Introduction: Magneto-optics (MO) technology is believed to be far more advanced in the former Soviet Union when compared to the US. This is evidenced by the existence of factories geared for the production of Yttrium Iron Garnet (YIG) wafers. The potential advantages to MO Crystal Technology over other magnetic sensing technologies are (1) light weight and compact construction, (2) low cost, a...

Epitaxial Magnetic Garnet Heterostructures

A summary of our recent progress in the growth and characterization of magnetic and magnetooptic garnet heterostructures is presented in this paper. The similarity in crystal chemistry and lattice parameters among the various garnets (yttrium iron garnet, bismuth iron garnet, etc.) is utilized to create artificially layered heterostructures and superlattices. Rare earth (especially Eu) substitu...
