| Popis: | Photoinduced magnetic phenomena are considered in yttrium–iron single-crystalline garnets grown from a BaO–B2O3 molten solution with the addition of iridium to the initial melt. The features of the composition and defects of the crystal structure of the samples in the surface layer are determined. In view of this, explanations for features of the photoinduced magnetic phenomena in the investigated crystals are proposed. The determining role of oxygen anions for the photoinduced magnetic phenomena at room temperature is highlighted, and the possible role of a variation in the dopant content and composition is considered. |
