    Xuduudaha farsamada

    Qalabka 'GGG / SGGG / NGG Garnets' waxaa loo isticmaalaa epitaxy dareere ah. SGGG subatrates waa u gogol xajista filimka 'magneto-optical'. Qalabka aaladda isgaarsiinta indhaha, waxay u baahan yihiin in badan oo la adeegsado 1.3u iyo 1.5u isolator optical, waa qeyb muhiim ah waa YIG ama BIG filim lagu meeleeyay aag magnet ah. 
    SGGG substrate wuxuu ku fiican yahay sii kordhinta bismuth-beddelka bir garnet epitaxial, waa qalab wanaagsan oo loogu talagalay YIG, BiYIG, GdBIG.
    Waa waxyaabo jireed iyo farsamo wanaagsan iyo xasiloonida kiimikada.
