Abstract
Ce-substituted fibrous YIG (Y3-XCeXFe5O12; Ce:YIG) single crystals wer e successfully grown by a floating zone method using YAG laser heating . We observed that Ce:YIG crystals show uniform distribution of Ce in the YIG crystal and an excellent magnetooptical property in the near-i nfrared region up to the Ce substitution of X = 0.3. However, the solu bility limit of Ce into the YIG crystal was confirmed to be approximat ely 0.3 in our growth method, by the composition analysis, lattice con stant and Faraday rotation measurements. Ce-substituted MG with X = 0. 3 shows a large Faraday rotation and small optical absorption coeffici ent in the wavelength region of 1.51-1.57 mu m and is expected to be a pplicable to the optical isolator.
