通过施加强磁场实现了金纳米球的二维结晶。这种现象是基于由磁场引起的两种不同的力;磁偶极子之间的相互作用在磁球中感应和磁场梯度产生的磁力。前一种力通常很弱，因此可以忽略不计。然而，在适当的条件下，我们可以实现这两种力量之间的微妙平衡。这种现象是一类新的自组装现象，我们相信我们的成就将是磁场利用的里程碑。
Two-dimensional crystallization of nonmagnetic gold spheres was achieved by the application of a high magnetic field. This phenomenon is based on the two different forces caused by a magnetic field; interactions between magnetic dipoles induced in the nonmagnetic spheres and magnetic force derived from field gradient. The former force is generally so weak and, hence, negligible. However, under an appropriate condition, we can achieve the subtle balance between the two forces. This phenomenon is a new class of self-assembling phenomena, and we believe that our achievement will be a milestone in the utilization of magnetic fields.
