Ce9.33(SiO4)6O2　(CSO)　crystals　were　grown　by　the　Czochralski　(Cz)　method.　Rietveld　refinement　of　XRD　patterns　confirmed　the　oxyapatite　structure　of　CSO,　XPS　analysis　revealed　the　valence　of　Ce　ions　in　CSO　crystals.　Magnetization　curve　and　temperature　dependencies　of　the　magnetic　susceptibility　were　measured,　paramagnetic　behavior　and　magnetic　anisotropy　have　been　observed.　Photoluminescence　and　Faraday　rotation　characteristics　of　the　CSO　crystal　were　investigated　at　room　temperature.　Verdet　constants　of　CSO　were　about　1.6　times　as　large　as　those　of　TGG.　Baesd　on　Van　Vleck-Hebb　theory,　the　effective　transition　wavelength　and　probability　of　CSO　crystal　were　calculated　and　compared　with　other　Ce3+-containing　crystals.　The　absorption　and　magnetic　circular　dichroism　(MCD)　spectra　of　4f　-＞　5d　transitions　in　Ce3+　ions　in　CSO　crystal　were　studied.
