本文讨论了Y2O3-Fe2O3-Bi2O3-PbO·0.2B2O3赝四元系相图的得出与运用;用Bi2O3-PbO-B2O3做助熔剂,获得了磁性石榴石Y3-xBixFe5O12单晶(0≤x≤1.2);还论述了Bi-YIG晶体内Bi含量与助熔剂熔液成份的关系。The pseudo quaternary system phase diagram of Y2O3-Fe2O3-Bi2O3-PbO·0.2B2O3 is obtained and used. Single crystals of the ferrimagnetic garnet Y3-xBixFe5O12(O≤x≤ 1.2) are grown by using Bi2O3-PbO-B2O3 flux systems. The dependences of the content Bi (x) in the single crystals of Bi-YIG on the compositions of the solutions arediscussed.
