    Imingcele yobuchwepheshe

    Ama-garnet we-GGG / SGGG / NGG asetshenziselwa i-epitaxy ewuketshezi. ibekwe kumandla kazibuthe. 
    I-substrate ye-SGGG inhle kakhulu ekukhuleni kwama-bismuth-substituted iron garnet epitaxial films, kuyinto enhle ye-YIG, BiYIG, GdBIG.
    Kuhle izakhiwo zomzimba nezomshini nokuzinza kwamakhemikhali.
    Izicelo:
    YIG, BIG epitaxy ifilimu;
    Imishini yama-microwave;
    Faka esikhundleni i-GGG
