    Xuduudaha farsamada

    Gallium Gadolinium Garnet (Gd3Ga5O12 ama GGG) hal crystal waa walxo leh muuqaalo wanaagsan, farsamo iyo kuleyl taasoo ka dhigaysa mid rajo u leh in loo isticmaalo soo saarista qaybaha indhaha ee kala duwan iyo sidoo kale walxaha substrate ee filimada magneto-optical iyo heerkulka sare ee superconductors. Maaddada ugu fiican ee substrate-ka ee go'doominta indhaha infrared (1.3 iyo 1.5um), oo ah aalad aad muhiim u ah isgaarsiinta indhaha.Waxay ka samaysan tahay YIG ama filim BIG ah oo ku yaal substrate GGG oo lagu daray qaybo birefringence ah.Sidoo kale GGG waa substrate muhiim u ah go'doominta microwave iyo aaladaha kale.Sifooyinkeeda jidheed, makaanikada iyo kiimikaad ayaa dhamaantood u fiican codsiyada kor ku xusan.

    Codsiyada ugu muhiimsan:
    Cabirrada waaweyn, laga bilaabo 2.8 ilaa 76mm.
    Khasaaraha indhaha oo hooseeya (<0.1%/cm)
    Dhaqdhaqaaqa kulaylka sare (7.4W m-1K-1).
    Heerka waxyeelada laysarka sare (> 1GW/cm2)
