Interferometric Detection of Pinned Interactions in Bismuth-Substituted Iron Garnet

Optical and magnetooptical properties of bismuth and gallium substituted iron garnet films

A series of iron garnet films of composition Lu Bi Fe Ga O grown on (100) oriented GGG substrates have been studied 3yx x 5yy y 12 using variable angle spectroscopic ellipsometry and polar Kerr spectroscopy (MOKE). The diagonal and off-diagonal components of the permittivity tensor have been determined in the range 1–5 eV. Our results seem to be in accordance with previously reported measuremen...

Anisotropy of Ruthenium-substituted Yttrium-iron-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...

Excitation of magnetic precession in bismuth iron garnet via a polarization-independent impulsive photomagnetic effect

Magnetic and Optical Studies of Structure of Co-Doped Bismuth-Iron-Garnet

Using an alternating reactive ion &am sputtering technique, Co ion was doped in epitaxially growing Bi3Fe5Ol, garnet film. The intense enhancement of magnetization, coercivity, and optical absorption at 633nm was observed. The Faraday hysteresis loop for slightly Cwdoped film showed anomalous behavior. Those phenomena can be understood considering the composite film structure in which fine part...
