SGGG
Sggg crystal, namely Ca Mg Zr doped gadolinium gallium garnet, is an excellent substrate material for Bi Fe garnet epitaxial films.
-
LaAlO3
LaAlO3 crystal is the substrate material for epitaxial growth of high temperature superconducting thin films and giant magnetoresistance thin films because of its good lattice matching with a variety of perovskite structure materials.
