Abstract
Bi-substituted rare-earth iron garnet Tb2.40Bi0.60Ga0.13Fe4.87O12 (TbBiGaIG) films on magnetic rare-earth iron garnet Tb0.87Yb1.60Bi0.53Fe5O12 (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.
