GGG Substrate
Fa'amatalaga
Gallium Gadolinium Garnet (Gd3Ga5O12poʻo le GGG) tioata tasi o meafaitino ma mea lelei faʻapitoa, masini ma mea vevela lea e faʻamaonia ai mo le faʻaogaina o mea faʻapitoa eseese faʻapea foʻi ma mea faʻapipiʻi mo ata tifaga magneto-optical ma superconductors maualuga-vevela. infrared optical isolator (1.3 ma 1.5um), o se masini taua tele i fesoʻotaʻiga faʻapitoa.E faia i le YIG po'o le BIG ata i luga o le GGG substrate fa'atasi ai ma vaega birefringence.E le gata i lea, o le GGG o se mea taua mo le microwave isolator ma isi masini.O mea fa'aletino, masini ma kemisi e lelei uma mo fa'aoga i luga.

GGG Substrate Fa'amatalaga
GGG substrate e fa'atatau i se mea fa'apipi'i e faia i mea tioata gadolinium gallium garnet (GGG).O le GGG o se mea fa'apipi'i tioata fa'apipi'i e aofia ai elemene gadolinium (Gd), gallium (Ga) ma le okesene (O).
GGG substrates o loʻo faʻaaogaina lautele i masini magneto-optical ma spintronics ona o latou mea sili ona lelei maneta.O nisi o mea taua o GGG substrates e aofia ai:
1. Malamalama maualuga: GGG o loʻo i ai le tele o faʻasalalauga i le infrared (IR) ma le vaʻaia o alaleo malamalama, talafeagai mo faʻaoga mata.
2. Magneto-optical properties: GGG faʻaalia malosi magneto-optical aafiaga, e pei o le Faraday aafiaga, lea o le polarization o le malamalama e ui atu i le mea o loʻo sui i le tali atu i se maneta faʻaaogaina.O lenei meatotino e mafai ai ona atinaʻe le tele o masini magneto-optical, e aofia ai isoltors, modulators, ma sensors.
3. Maualuluga vevela maualuga: GGG e maualuga le faʻamautuina o le vevela, lea e mafai ai ona faʻasaga i le vevela maualuga e aunoa ma le faʻaleagaina tele.
4. Faʻalauteleina le vevela maualalo: GGG e maualalo le faʻaogaina o le faʻalauteleina o le vevela, faʻatasi ai ma isi mea e faʻaaogaina i le faʻaogaina o masini ma faʻaitiitia ai le lamatiaga o le toilalo ona o le mamafa o masini.
GGG substrates e masani ona faʻaaogaina e fai ma mea faʻapipiʻi poʻo paʻu paʻu mo le tuputupu aʻe o ata manifinifi poʻo fausaga faʻalautele i masini magneto-optical ma spintronic.E mafai foi ona faʻaaogaina e fai ma mea faʻapipiʻi Faraday poʻo elemene faʻamalosi i lasers ma masini e le faʻaogaina.
O nei substrates e masani ona gaosia e ala i le faʻaaogaina o auala faʻatupu tioata eseese e pei ole Czochralski, flux poʻo le solid state reaction techniques.Ole auala fa'apitoa e fa'aogaina e fa'alagolago ile maualuga ole substrate GGG mana'omia ma le tele.
