INVESTIGATION OF THE INFLUENCE OF Ca*992*99+, Si*994*99+ ION ADMIXTURES AND IONIC IRRADIATION ON OPTICAL AND MAGNETOOPTICAL PROPERTIES OF YTTRIUM IRON GARNET

Monocrystals and epitaxial films of yttrium iron garnet are considered in the paper aiming at the investigation of the influence of O*992*99+ irradaitaon and alloying by Si*994*99+ and Ca*992*99+ ions on optical and magnetooptical properties of yttrium iron garnet. The clarification of the nature of a charging neutralization mechanism and the nature of the additional absorption of yttrium iron garnet in the spectrum IR-region is also the aim of the paper. As a result the influence of Si*994*99+, Ca*992*99+ ion admixtures and irradiation by O*992*99+ ions on optical and magnetooptical properties of yttrium iron garnet has been investigated. Optimum concentrations of the measuring by Si*994*99+ and Ca*992*99+ ions for the transparence increase of yttrium iron garnet monocrystals have been determined as well as optimum doses of the irradiation by O*992*99+ ions for epitaxial films of yttrium iron garnet, doses improving their crystalline structure and transparence.
