A new piezoelectric single crystal, Sr3Ga2Ge4O14 (SGG), has been grown successfully by the vertical Bridgman method with crucible-sealing technique. SGG crystal up to 2″ in diameter has been obtained. The relative dielectric constants, the piezoelectric strain constants, elastic compliance constants and electromechanical coupling factors have been determined with resonance and anti-resonance frequencies method by using the impedance analyzer (Agilent 4294A). The results show that the piezoelectric strain constants and electromechanical coupling factors of SGG single crystal are higher than those of LGS single crystals making it a potential substrate material for surface-acoustic wave applications.

YFeO3 and other rare earth substituted crystals with distorted orthorhombic pervoskite-like structure (space group, 𝑃𝑏𝑛𝑚) have attracted much attention due to their remarkable magnetic properties of primary significance for technological applications. In the present work, the floating zone growth of YFeO3 crystals has been systematically investigated and high quality YFeO3 crystal was obtained by optimized process. The magnetic properties of YFeO3 crystal were investigated, and it indicated the high magneto-optical property in YFeO3 crystals with specific orientation due to its anisotropy. YFeO3 crystals display superior performance in the application magneto-optical current sensors and fast latching optical switches.
