基于透明陶瓷的磁光材料为现代法拉第隔离器提供了很好的机会。采用共沉淀法制备了高透过率的Ti、Ce共掺杂Tb 3Ga 5 O 12（Ti/Ce：TGG）陶瓷。Ti/Ce：TGG磁光陶瓷在1500 °C左右烧结8 h，磁光性能最好。值得注意的是，所制备的陶瓷在550-1450 nm的波长处呈现出最高的透射率，对应于81.0%。用场发射扫描电镜（FE-SEM）观察到样品中没有第二相或明显的气孔。Ti/Ce：TGG陶瓷在1064.0 nm处的费尔德常数高达65.5 rad m− 1 T −1，远高于纯TGG陶瓷。Ti/Ce：TGG陶瓷优异的光学和磁光性能使其成为一种极具吸引力的磁光材料。
Magneto-optical materials based on transparent ceramics are providing promising opportunities for modern Faraday isolators. Titanium (Ti),Cerium (Ce), co-doped Tb3Ga5O12(Ti/Ce:TGG) ceramics with high transmittance were prepared using the coprecipitated powders. The Ti/Ce:TGG magneto-optical ceramic with best quality was sintered at around 1500 °C for 8 h. It is noted that as-prepared ceramic presents the highest transmittance, corresponding to 81.0% at the wavelengths of 550–1450 nm. No secondary phase or obvious pores can be detected from the sample using field emission scanning electron microscopy (FE-SEM). The Verdet constant of Ti/Ce:TGG ceramic at 1064.0 nm is as high as 65.5 rad m−1T−1, which is much higher than that of pure TGG ceramic. The excellent optical and magneto-optical properties make Ti/Ce:TGG ceramic an attractive magneto-optical material.
