Preparation and Characterization of Cerium Substituted Bismuth Dysprosium Iron Garnets for Magneto-Optic Applications

摘要

We report on cerium substituted bismuth dysprosium iron garnet of composition Bi1.3Ce0.3Dy1Fe5O12 prepared by biased target ion beam deposition on a fused quartz substrate and postdeposition crystallization through rapid thermal annealing in air. The resulting thin film garnet achieved promising magnetic and magneto-optic (MO) properties on a low cost amorphous substrate and with reduced thermal budget toward potential MO applications and semiconductor processing for films of similar composition.
