Gawo la GGG
Kufotokozera
Gallium Gadolinium Garnet (Gd3Ga5O12kapena GGG) single crystal ndi zinthu zokhala ndi mawonekedwe abwino, makina ndi matenthedwe zomwe zimapangitsa kuti zikhale zodalirika kuti zigwiritsidwe ntchito popanga zinthu zosiyanasiyana zowoneka bwino komanso gawo laling'ono la mafilimu a magneto-optical ndi ma superconductors otentha kwambiri. infuraredi kuwala isolator (1.3 ndi 1.5um), chomwe ndi chipangizo chofunika kwambiri kuwala kuwala.Amapangidwa ndi filimu ya YIG kapena BIG pagawo laling'ono la GGG kuphatikiza magawo awiri awiri.Komanso GGG ndi gawo lofunikira la microwave isolator ndi zida zina.Mawonekedwe ake akuthupi, makina ndi mankhwala onse ndiabwino pazogwiritsa ntchito pamwambapa.

Tanthauzo la Gawo la GGG
Gawo laling'ono la GGG limatanthawuza gawo lapansi lopangidwa ndi gadolinium gallium garnet (GGG) crystal material.GGG ndi gulu lopangidwa ndi crystalline lopangidwa ndi zinthu gadolinium (Gd), gallium (Ga) ndi mpweya (O).
Magawo a GGG amagwiritsidwa ntchito kwambiri pazida za magneto-optical ndi spintronics chifukwa champhamvu kwambiri yamaginito ndi kuwala.Zina zazikulu za magawo a GGG ndi awa:
1. Kuwonekera kwakukulu: GGG ili ndi njira zambiri zotumizira mu infrared (IR) ndi kuwala kowoneka bwino, koyenera kugwiritsa ntchito kuwala.
2. Magneto-optical properties: GGG imasonyeza zotsatira zamphamvu za magneto-optical, monga Faraday effect, momwe kuwala kwa kuwala kumadutsa muzinthuzo kumazungulira potsatira mphamvu ya maginito yogwiritsidwa ntchito.Katunduyu amathandizira kupanga zida zosiyanasiyana za magneto-optical, kuphatikiza zodzipatula, ma modulators, ndi masensa.
3. Kukhazikika kwapamwamba kwa kutentha: GGG imakhala ndi kutentha kwapamwamba kwambiri, komwe kumapangitsa kuti ikhale yolimba kutentha kwapamwamba popanda kuwonongeka kwakukulu.
4. Kuwonjezeka kwa kutentha kwapansi: GGG ili ndi gawo lochepa la kuwonjezereka kwa kutentha, zomwe zimapangitsa kuti zigwirizane ndi zipangizo zina zomwe zimagwiritsidwa ntchito popanga zipangizo komanso kuchepetsa chiopsezo cholephera chifukwa cha kupanikizika kwa makina.
Magawo a GGG amagwiritsidwa ntchito ngati magawo ang'onoang'ono kapena zigawo zotchingira pakukula kwa mafilimu opyapyala kapena ma multilayer mu zida za magneto-optical ndi spintronic.Atha kugwiritsidwanso ntchito ngati zida za Faraday rotator kapena zinthu zogwira ntchito mu ma lasers ndi zida zosagwirizana.
Magawo awa nthawi zambiri amapangidwa pogwiritsa ntchito njira zosiyanasiyana zakukulira makristalo monga Czochralski, flux kapena njira zolimba zamachitidwe.Njira yeniyeni yomwe imagwiritsidwa ntchito imadalira mtundu ndi kukula kwa gawo lapansi la GGG.
