摘要
A calculation of the magnetic single-ion anisotropy in hematite has been made.The results show that an equivalent single-ion anisotropy field Hsi(=103.8×10^(2) Oe)exists along the c-axis at T=0K.The Morin transition in hematite could be explained by our results in conjunction with the calculated H_(md) by Artman et al.
