“…11,12 In order to obtain a congruent melt, a novel magneto-optical crystal, Tb 3 Sc 2 Al 3 O 12 (TSAG), was harvested by the replacement of Al 3+ with Sc 3+ in octahedral sites, but easy cracking characteristics of TSAG hinder its applications. 13 In addition, a Lu-modified TSAG crystal, namely TSLAG, was also designed. Both TSAG and TLSAG preserve excellent magneto-optical performance analogous to the TAG crystal, with a Verdet constant of 25% higher than that of TGG.…”

“…Researchers try to control the crystal structure by using the doping method, which can make the TAG crystal form a uniform melt at high temperature. , The scandium aluminum garnet crystal Tb 3 Sc 2 Al 3 O 12 (TSAG) was obtained by replacing Al 3+ at the octahedral position in the TAG lattice with Sc 3+ . − The ionic radius of Sc 3+ is 0.0745 nm, which is between 0.0923 nm of Tb 3+ and 0.0535 nm of Al 3+ . It can stabilize the garnet structure and make it possible to grow large-size and high-quality TSAG crystals with the Cz method. − …”

Terbium scandium aluminum garnet crystals (Tb3Sc2Al3O12, TSAG) have excellent optical comprehensive properties with unique competitive advantages in the Verdet constant and anti-laser damage threshold. However, the component segregation will easily occur during the growth of the TSAG crystal and the distribution habits of elements in crystals have not been systematically studied. A series of TSAG crystals with different compositions were grown by the Czochralski method in this work. The behaviors of Sc3+ and Al3+ in TSAG crystal growth were discussed, and the relationship between TSAG crystal cracking and crystal structure was deeply studied. The results show that the segregation coefficient of Al in the TSAG melt solid system is 1.02–1.03, while that of Sc is 0.94–0.97. It is observed by spherical aberration-corrected transmission electron microscopy that Sc3+ entered into the dodecahedron in the space where Tb3+ was located during the crystal growth, which explains that the composition ratio of Tb:(Al + Sc) in TSAG crystals was less than the stoichiometric ratio of 3:5. Crystals with a lower Sc content are not easy to crack during the growth and have high light transmittance (>80%), excellent thermal stability, and stronger magneto-optical properties.

“…In high‐power laser system, optical isolator based on the nonreciprocal Faraday effect is a no‐negligible passive component as it can effectively isolate the deleterious backlight, which is conducive to reducing the damage to the laser source and ensuring the stability of the systems 1–6 . In pace with the development of magneto‐optical isolators toward high power, miniaturization, and low cost, 7–10 more stringent requirements are being placed on the properties of magneto‐optical materials, mainly including high Verdet constant, large size, good optical quality, high thermal conductivity, outstanding laser damage threshold, and so on 11–17 .…”

Transparent terbium aluminum garnet (TAG)‐based ceramics were fabricated by vacuum pre‐sintering and hot isostatic pressing (HIP) posttreatment from the co‐precipitated TAG powders with different stoichiometric ratios. After component optimization, the transparent ceramics with TAG single‐phase and attractive optical quality were obtained. The in‐line transmittance of optimal Tb(1+x)3(Al0.996255Si0.003745)5O12.0093625+3x/2 (x = −.004, −.002) ceramics (1.7‐mm thick) pre‐sintered at 1700°C for 20 h with HIP posttreatment at 1700°C for 3 h under 176‐MPa Ar reaches 82.6% at the wavelength of 1064 nm. With increasing terbium components, the secondary phase TAP appears in ceramics, which significantly degrades the optical quality of TAG‐based ceramics. The Verdet constant of the TAG‐based ceramics at 632.8 nm is about −181 rad T−1 m−1 at room temperature, which is about 33% higher than that of the TGG single crystals (−134 rad T−1 m−1).
