GSGG Crystals
GGG / SGGG / NGG Garnets yog siv rau cov kua epitaxy.SGGG subatrates yog nplooj siab substrates rau magneto-optical zaj duab xis.In cov khoom siv kho qhov muag, xav tau ntau ntawm kev siv 1.3u thiab 1.5u optical cais, nws cov ntsiab lus tseem ceeb yog YIG lossis BIG zaj duab xis. tau muab tso rau hauv ib qho chaw sib nqus.
SGGG substrate yog zoo heev rau loj hlob bismuth-hloov hlau garnet epitaxial films, yog cov khoom zoo rau YIG, BiYIG, GdBIG.
Nws yog qhov zoo ntawm lub cev thiab kev siv tshuab thiab tshuaj lom neeg ruaj khov.
