摘要

采用光学浮区法生长了新型磁光晶体YFeO3, 通过工艺优化, 获得了φ(7～10)mm、长度约60mm的YFeO3晶体. XRD分析表明晶体具有正交钙钛矿结构, 晶格常数a=5.5964A, b=7.6052A, c=5.2842A. 晶体生长界面为凸界面, 生长取向接近[100]方向.晶体截面抛光后观察, 未发现肉眼可见的包裹体、晶界等缺陷.

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
