Iikristale zeGSGG
I-GGG/SGGG/NGG Iigarnets zisetyenziselwa i-epitaxy engamanzi.I-SGGG subatrates yi-substrates ezinikeleyo yefilimu yemagneto-optical.Kwizixhobo zonxibelelwano lwe-optical, zifuna kakhulu ukusebenzisa i-1.3u kunye ne-1.5u yokuhlukanisa i-optical isolator, icandelo layo eliphambili yifilimu ye-YIG okanye ye-BIG. ibekwe kumhlaba wemagnethi.
I-substrate ye-SGGG igqwesileyo ekukhuliseni iifilimu ze-bismuth-intsimbi ye-garnet epitaxial, yinto efanelekileyo ye-YIG, i-BiYIG, i-GdBIG.
Yimpahla elungileyo yomzimba kunye noomatshini kunye nokuzinza kweekhemikhali.
Usetyenziso:
I-YIG, ifilimu enkulu ye-epitaxy;
izixhobo zeMicrowave;
Indawo ye-GGG
