Once they meet with magnets, ferromagnetic materials inside the "small magnets" reordering, same direction, magnetic, and make mutual superposition ferromagnetic materials display macro magnetism.

一旦它们与磁铁相遇，铁磁性物质内部的“小磁铁”重新排序，方向相同，磁性互相叠加，于是使铁磁性物质显示宏观磁性。

The results show that the effective exchange integral values are less than zero under different conformations, so the radicals display the anti-ferromagnetic coupling.

结果表明，不同构象下各体系有效交换积分值都小于零，自由基间表现为反铁磁性耦合。
