GGG/SGGG/NGG Garnets amagwiritsidwa ntchito ngati epitaxy yamadzimadzi.SGGG subatrates ndi gawo lodzipereka la filimu ya magneto-optical.Muzida zoyankhulirana zowoneka bwino, zimafunikira kugwiritsa ntchito 1.3u ndi 1.5u optical isolator, chigawo chake chachikulu ndi filimu ya YIG kapena BIG. adayikidwa mu magnetic field.
Gawo laling'ono la SGGG ndilabwino kwambiri pakukulitsa mafilimu a bismuth-substituted iron garnet epitaxial, ndi zinthu zabwino za YIG, BiYIG, GdBIG.
Ndi zabwino thupi ndi makina katundu ndi mankhwala bata.
Mapulogalamu:
filimu ya YIG, BIG epitaxy film;
Zipangizo za Microwave;
Mtengo wa GGG
