对静磁相互作用耦合的二维磁点阵列从面内磁化态到面外磁化态的重定向转变进行了理论研究。纳米级圆柱点的方格是在假设点是软磁且具有均匀磁化的情况下考虑的。本研究预测，点间静磁耦合决定了此类磁点密堆积阵列的重新定向转变。根据目前的计算讨论了纳米级单域点阵列的最新实验结果。
A theoretical study on the reorientational transition from in-plane to out-of-plane magnetized state is performed for two-dimensional magnetic dot arrays coupled by magnetostatic interaction. The square lattice of nanoscale cylindrical dots is considered with the assumptions that the dots are magnetically soft and they have uniform magnetization. The present study predicts that the interdot magnetostatic coupling determines the reorientation transition for close-packed arrays of such magnetic dots. Recent experimental results on the nanometer-scale single-domain dot arrays are discussed in light of the present calculation.
