文摘
- •
New substrate crystals of CLNGG and LCLNGG were successfully grown by Czochralski method.
- •
Lattice-mismatch and Ga2O3 volatilization are major inducements of crack and inclusion defects.
- •
LCLNGG crystal has a more perfect structure by doping Li+, Nb5+, and La3+ ions.
- •
LCLNGG crystals may be a better candidate substrates for highly Bi or Ce doped-YIG film.
