利用经典Heisenberg模型的Luttinger-Tisza方法，研究了等容畸变对具有立方Laves相结构的YMn 2自旋阻挫系统的影响.微扰计算考虑了交换参数的距离依赖性。结果表明，在四角畸变的影响下，自旋系统的有序化为层状组态或YMn 2型组态.
By making use of the Luttinger-Tisza method on the classical Heisenberg model, we examine how the isochoric distortions affect the frustrated spin system in YMn 2 with the cubic Laves phase structure. The distance dependece of the exchange parameter is taken into account by perturbational calculation. It is shown that the spin system orders in layered configurations or the YMn 2 type configuration under the influence of tetragonal distortion.
