Abstract

We have investigated the magneto-optical and optical properties of the ion implanted (YBiCaSmLu)₃(FeGeSi)₅O₁₂ garnet films. It has shown that the ion implantation influences significantly the magneto-optical properties of the garnet films and practically does not change its optical characteristics. In the proceeding, we have researched the magneto-optical properties of ion implanted (YBiCaSmLu)₃(FeGeSi)₅O₁₂ garnet films after it was annealed at 270degC. This kind of the experiment is particularly interesting in the matter of annealing process as it reduces the implantation defects and restores crystalline structure of ferrite garnet. We have also determined the spectral dependences of the component of the tensor of dielectric permittivity for the surface of the ferrite-garnet films before and after implantation process. These calculations let us evaluate the influence of implantation on an electronic energy structure of the surface layer for the sample.
