Abstract
The Bi1Dy2Fe4.3Al0.7O12 films with perpendicular anisotropy were successfully prepared by citric acid complex type sol-gel method. The properties of Bi-substituted garnet films annealed at different temperatures were investigated. The results indicated the garnet films had high squareness. The coercive force of the films was about 1100 Oe. The figures of merit of 2° at 430 nm and 1.5° at 520 nm were obtained. The best crystallization temperature was 650°C.
