Gadolinium gallium garnet (GGG) is used for a magneto-optical film (YIG thin film or BIG) a special substrate in the optical communication apparatus

MgO is an excellent  single crystal substrate for thin films of Ferro magnetic, Photo-electronic and  high Tc superconductor materials. 

Sapphire substrate is the popular substrates for III-V nitrides, superconductor and magnetic epi film due to less mis-matched lattice and stable chemical and physical properties
