在横向磁场中用 Bridgman法生长的晶锭其轴向组分分布在中部和尾部具有相同的趋势,在头部有三种类型的分布磁场通过对固液混合区对流的作用影响溶质的再分布和轴向组分分布突然施加磁场和中断磁场都引起轴向组分分布的突变.当安瓿绕生长轴匀速旋转时、晶锭的径向组分分布既没有安瓿不旋转时的偏心特征,也没有常规 Bridgman法生长晶体的径向对称性尾部呈现圆锥状的凸起,可能是旋转生长抑制胞状结构的证据
In the transverse magnetic field, the ingot grown by the Bridgman method has the same tendency of the axial component distribution in the middle and the tail. There are three types of distributed magnetic fields in the head that influence the redistribution of solute through the convection of the solid-liquid mixing region and Axial component distribution Sudden application of magnetic field and interruption of the magnetic field caused by the axial component of the mutation. When the ampoule is rotated at a constant speed around the growth axis, the radial component distribution of the ingot is neither eccentric nor when the ampoule is not rotating nor is the radial symmetry of the grown crystal by conventional Bridgman method. The tail presents a conical bulge, possibly rotating Evidence of growth inhibition of cellular structure
