Growth and Characterization of (TbBiGaIG) Film/(TbYbBiIG) Crystal Composite

Abstract

Bi-substituted rare-earth iron garnet Tb_2.40Bi_0.60Ga_0.13Fe_4.87O₁₂ (TbBiGaIG) films on magnetic rare-earth iron garnet Tb_0.87Yb_1.60Bi_0.53Fe₅O₁₂ (TbYbBiIG) substrates were grown by a liquid phase epitaxy (LPE) technique. The microstructure and magneto-optical properties of TbBiGaIG film/TbYbBiIG crystal composite were investigated. The (110)-oriented TbBiGaIG single crystal film was epitaxially grown on the TbYbBiIG substrate. The TbBiGaIG film/TbYbBiIG crystal composite showed an improved temperature dependence of Faraday rotation because of the compensation effect.
