金属自由基聚合物（Co（hfac）（2）BPNN）在6 K下显示出非常大的矫顽场52 kOe（4.1 MA m（-1）），表明它是有史以来报道的最硬的磁体。高于10 K，出现软字符，由于磁化重取向的快速动力学。
A metal-radical polymer (Co(hfac)(2) BPNN] showed a very large coercive field of 52 kOe (4.1 MA m(-1)) at 6 K, indicating that it is the hardest magnet ever reported. Above 10 K, a soft character appeared, owing to the fast dynamics of magnetization reorientation.
