I-Gallium Gadolinium Garnet (Gd3Ga5O12 okanye GGG) ikristale enye iyinto ebambekayo eneempawu ezintle zokubona, oomatshini kunye ne-thermal eyenza ukuba ibe nethemba lokusetyenziswa ekwenzeni izinto ezahlukeneyo zamehlo kunye nemathiriyeli engaphantsi kweefilimu zemagneto-optical kunye nobushushu obuphezulu be-superconductors. eyona nto ilungileyo ye-substrate ye-infrared optical isolator (1.3 kunye ne-1.5um), eyona sixhobo esibaluleke kakhulu kunxibelelwano lwe-optical.Yenziwe ngefilimu ye-YIG okanye ye-BIG kwi-substrate ye-GGG kunye neendawo ezidibeneyo.Kwakhona i-GGG yi-substrate ebalulekileyo ye-microwave isolator kunye nezinye izixhobo.Iimpawu zayo zomzimba, oomatshini kunye neekhemikhali zonke zilungile kwezi zicelo zingentla.
Usetyenziso oluphambili:
Imilinganiselo emikhulu, ukusuka kwi-2.8 ukuya kwi-76mm.
Ilahleko yamehlo ephantsi (<0.1%/cm)
Ukuhanjiswa kwe-thermal ephezulu (7.4W m-1K-1).
Umda womonakalo welaser ophezulu (> 1GW/cm2)
