| 摘 要： | 首次用激光布里渊散射方法，研究了自旋波劲度系数Ｄ随温度Ｔ的变化关系，得到了ＢＣＶＩＧ单晶的从室温到居里点温度附近Ｄ～Ｔ关系。基于自旋波之间相互作用的理论，对实验结果进行了合理的解释。

| Abstract: | he temperature dependence of the spin-wave stiffness constant has beenstudied by laser Brillouin scattering for the first the.The temperature dependence of thespin-wave stiffness constant for BCVIG single crystals has been obtained.The relation ofD and T is satisfactorily explained on the basis of the interaction between the optical andacoustical magnon branches. |
