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.
