强相互作用量子自旋系统ESR谱线形状的场和温度依赖性将为磁相互作用提供各种重要信息。本文介绍了一种用Kubo公式直接计算动力学磁化率的方法，并将其应用于各种晶格结构的自旋系统。在那里，ESR线的形状表现出显着的依赖于场的强度，也对场的方向和晶格轴之间的几何位置。
The field and temperature dependence of the line shape of ESR for strongly interacting quantum spin systems would provide various important informations for the magnetic interaction. We have introduced a method of direct numerical estimation of the dynamical susceptibility with the Kubo formula and applied it to spin systems of various lattice structures. There the ESR line shape shows significant dependence on the strength of the field, and also on the geometrical situation among the directions of the fields and lattice axes.
