Abstract:

Novel magneto-optical crystal YFeO3 (yttrium orthoferrite) was grown by the floating zone method. The growth parameters were optimized and YFeO3 single crystal up to 7--10mm in diameter and 60mm in length was obtained. XRD patterns show that it has orthorhombic perovskite structure with a=5.5964A, b=7.6052A, c=5.2842A. The solid-liquid interface is convex to the melt and the growth direction is close to [100] direction. No visible inclusions and grain boundaries are observed on the polished surface.

Key words: floating zone method, magneto-optical materials, YFeO3 crystal, crystal growth
