Tb 3 Al 2.5 Ga 2.5 O 12 Transparent Ceramic for Magneto‐Optical Application
The optical quality and microstructure of the Tb 3 Al 2.5 Ga 2.5 O 12 transparent ceramic were investigated and compared with those of Tb 3 Ga 5 O 12 ( TGG ) and Tb 3 Al 5 O 12 ( TAG ). The transmission of the Tb 3 Al 2.5 Ga 2.5 O 12 ceramic was as high as 80% in the visible and near‐infrared ( IR )...
