Crystals GSGG
GGG/SGGG/NGG Garnets waxaa loo isticmaalaa dareeraha epitaxy.SGGG substrates waxaa u heellan substrates for magneto-optical film.In qalabka isgaarsiinta indhaha, waxay u baahan yihiin wax badan oo ka mid ah isticmaalka 1.3u iyo 1.5u go'doomin indhaha, waxa ka mid ah xudunta u waa YIG ama BIG film. la geliyay goob birlab ah.
Substrate-ka SGGG wuxuu aad ugu fiican yahay koritaanka bismuth-ku beddelay filimada epitaxial iron garnet, waa wax u wanaagsan YIG, BiYIG, GdBIG.
Waa sifooyin jidheed iyo farsamo oo wanaagsan iyo xasilloonida kiimikada.
Codsiyada:
YIG, filim epitaxy BIG;
Aaladaha Microwave;
Beddelka GGG
