In this account, Dy(9.33-x)Lax(SiO4)6O2crystals were grown by the Czochralski technique, and their magneto-optical properties were examined. Rietveld structural refinement of XRD patterns illustrated Dy(9.33-x)Lax(SiO4)6O2possess hexagonal systemP63/m with oxyapatite structure. UV–Vis–NIR spectroscopy revealed higher transparency in the 420–700 nm spectral region when compared to PSO and TGG crystals. The magneto-optical properties and temperature dependence of magnetic susceptibility demonstrate that Dy8.36La0.97(SiO4)6O2crystals show paramagnetic behavior within the temperature range of 2–300 K and yield a Faraday rotation angle which is approximately 1.16-fold larger than that of Tb3Ga5O12crystals. Overall, Dy8.36La0.97(SiO4)6O2crystals look promising for applications in magneto-optical devices in the visible wavelength range.
