srco3p4o14的自旋体系为j1 - j1 - j2三聚自旋-3/2链。j1和j2交换相互作用分别为反铁磁性和铁磁性。然而，尽管对三聚自旋链的期望，1/3量子磁化平台并未出现。为了研究交换相互作用的符号，我们使用中子粉末衍射测量确定了磁性结构。j1和j2交换相互作用都是铁磁性的。先前报道的自旋系统是不正确的。因此，不存在1/3量子磁化平台。
The spin system in SrCo 3 P 4 O 14 was reported to be a J 1 – J 1 – J 2 trimerized spin-3/2 chain. The J 1 and J 2 exchange interactions were antiferromagnetic and ferromagnetic, respectively. However, in spite of expectation for the trimerized spin chain, a 1/3 quantum magnetization plateau does not appear. To investigate the sign of exchange interactions, we determined the magnetic structure using neutron powder diffraction measurements. Both the J 1 and J 2 exchange interactions are ferromagnetic. The previously reported spin system is incorrect. Therefore, no 1/3 quantum magnetization plateau exists.
