| Popis: | International audience; Tb3Sc2Al3O12 has been grown as a crystal showing high Faraday effect. A self-organized pattern, of directionally formed eutectic, has been observed at the edge of the Tb3Sc2Al3O12 microcrystals grown by the micro-pulling down method. Binary (Tb3Sc2Al3O12/TbScO3) and ternary eutectic (depending on the pulling rate and the composition) are formed at the edges showing a highly packed pseudo-hexagonal spot pattern (over large areas) in the cross section and a rod pattern (length up to 200 μm) in the longitudinal section. The size of the spot pattern can be controlled by the pulling rate. The observed arrays can be suitable for various photonic devices. |
