| 中文摘要 | the magnetic anisotropy in ytterbium iron garnet (ybig) is theoretically investigated under high magnetic fields (up to 160 koe). according to the crystal field effect in ytterbium gallium garnet (ybgag), a detailed discussion of crystal-field interaction in ybig is presented where a suitable set of crystal-field parameters is obtained. meanwhile, the influences of nine crystal-field parameters on the crystal-field energy splitting are analyzed. on the other hand, considering the ytterbium-iron (yb-fe) superexchange interaction of ybig, the spontaneous magnetization is calculated at different temperatures for the [111] direction. in particular, we demonstrate that the wesis constant lambda is the function of 1/t in ybig. in addition, the field dependences of the magnetization for the [110] and [111] directions are theoretically described where a noticeable anisotropy can be found. our theory further confirms the great contribution of anisotropic yb-fe superexchange interaction to the anisotropy of the magnetization in ybig. moreover, our theoretical results are compared with the available experiments. |
