现在我们将交换的概念扩展到包括整个三维（3-d）晶格的相互作用。这种相互作用不一定是长距离的，可能只对第一到第四近邻很重要，但这种影响在样本中的大距离上都能观察到。向这种长程有序的转变的特征在于特征比热异常和磁化率行为与上面描述的完全不同。换句话说，到有序状态的转变实际上是相变。
We now expand the concept of exchange to include interactions throughout a three-dimensional (3-d) crystalline lattice. The interactions are not necessarily long-range, and probably are important only for first through fourth nearest neighbors, but the effects are observed over large distances in a sample. Transitions to such long-range order are characterized by both characteristic specific heat anomalies and susceptibility behavior quite different from what has been described above. In other words, the transition to an ordered state is in fact a phase transition.
