| Abstract: | Cerium‐doped terbium gallium garnet single crystal having a large Verdet constant was grown by floating zone (FZ) method, which was suitable for the use in optical devices. The lattice parameters and the X‐ray rocking curve measurement of the crystal was determined by X‐ray diffraction analysis. The Verdet constant of the crystal (B = 0.55 T) at the wavelength of 632.8 nm was −165.8 rad m−1 T−1 at room temperature, 23.7% larger than that of pure TGG (−134.0 rad m−1 T−1). The performance of the high optical quality and excellent magneto‐optical properties of the crystal shows the great potential of using this new method to meet the increasing demand of VI‐NIR Faraday rotators. |
