Na2Tb4(MoO4)(7) crystals have been grown by the Czochralski technique for the first time for magnetooptical applications. Structure refinement of XRD data confirms that the compound crystallizes in the tetragonal system I4(1)/a, with scheelite structure. The as-grown crystal exhibits moderate thermal stability and weak thermal expansion anisotropy (alpha(c)/alpha(a) approximate to 1.08), and the hardness is about 4.7 Moh. Transmittance spectra indicated that the Na2Tb4(MoO4)(7) crystal presents a high transparency from 600 nm to 1500 nm after annealing in 02 atmosphere at 973 K for 20 h. The Faraday effect and the temperature dependence of the magnetic susceptibility have been investigated, which demonstrate that the Na2Tb4(MoO4)(7) crystal exhibits paramagnetic behavior over the experimental temperature-range 2300 K and yields a Faraday rotation which is about 1.6 times as large as that of Tb3Ga5O12 crystal. Na2Tb4(MoO4)(7) crystal is therefore a promising Faraday material in particular for new magneto-optical applications in the visible-near lR wavelength region. (C) 2015 Elsevier B.V.
