本文研究了软铁磁纳米线的微磁变分问题。我们证明，由于导线的直径很小，导线内部的磁化强度只取决于导线的长度变量。在这种情况下，导线的微磁能得到了极大的简化，为了找到最优的磁化分布，必须解决一维局部变分问题。微磁学;纳米线;Γ收敛。
In this paper we consider the micromagnetic variational problem for soft ferromagnetic nanowires. We show that, as the diameter of the wire is small, the magnetization inside the wire depends only on the length variable of the wire. The micromagnetic energy of the wire, in this case, is greatly simplified and in order to find the optimal magnetization distribution, one has to solve a one-dimensional local variational problem. micromagnetics; nanowire; Γ-convergence.
