Investigation of spiral bending of straight Czochralski grown
Dy 3 (Ga 1 − x Al x) 5 O 12 pseudo-binary single crystals were grown by the Czochralski method. The influence of Al 3+ ions on the spiral bending was investigated. Effective suppression of the spiral symptoms takes place at x = 0.4. In the case of x = 0−0.2 the spiral symptoms were observed in the tail part of crystals. In the case of x = 0.6 there are no spiral symptoms.
