| 摘 要： | 在单晶炉中成功生长出纵向长度为15.5 mm,横向线度约为0.5 mm的大尺寸Sm211晶须,表征了Sm211晶须的结构和成份.利用高温光学显微镜(HTOM)原位观察了Sm123在Sm211晶须上的外延生长并讨论了两者的关联.实验分析表明,在1 100℃观察到的针状高温相可能是Sm422相;在1 050℃的包晶温度,Sm123相在Sm211晶须上形成,显示出[001]Sm211//[100]Sm123 and[001]Sm211//[110]Sm123两个外延关联.

| Abstract: | The whisker of Sm2BaCuOδ compound is successfully grown by single crystal technique with a length of 15.5 mm and a diameter of 0.5 mm.The structure and composition are analyzed by EDX technique.By high temperature optical microscope(HTOM),the in-situ epitaxial growth process is observed and both relationships have been studied.A needle-shaped high temperature phase is observed at 1 100 ℃,which may be an Sm422 phase.At temperature 1 050 ℃,the Sm123 phase formed and show two epitaxial relations on the Sm211 whisker: Sm211//Sm123 and Sm211//Sm123. |
