•Tb9.33(SiO4)6O2 crystals were grown by the Czochralski method.•Structure refinement confirms that the compound crystallizes in the hexagonal system.•Tb9.33(SiO4)6O2 shows a higher visible transparency than Tb3Ga5O12.•The Verdet constant of Tb9.33(SiO4)6O2 is about 2.0 times as large as that of Tb3Ga5O12.
Tb9.33(SiO4)6O2 crystals have been grown by the Czochralski technique for the first time for magneto-optical applications. Rietveld structure refinement of XRD data confirms that the compound crystallizes in the hexagonal system P63/mP63/m, with oxyapatite structure. Transmittance spectra and the Faraday rotation have been investigated, which demonstrate that Tb9.33(SiO4)6O2 crystals show a higher visible transparency and a larger Faraday rotation than Tb3Ga5O12 crystals. Tb9.33(SiO4)6O2 is therefore a promising material in particular for new magneto-optical applications in the visible-near IR wavelength region.
