论文摘要
Na2snteo6在熔融盐混合物中的离子 - 交换处理导致玫瑰岩（PBSB2O6）相关的MNSNTEO6。它的晶体结构是通过Rietveld方法完善的。在SN/TE分布的三个可能模型中，该模型（P3 im，A = 5.23093（11）A，C = 4.62430（16）A是基于键距离的首选。但是，由于堆积的缺陷，因此每个人（SNTEO6）2-层保持了前体的完整订购，并且仅显示了堆积的缺陷。在Neel温度下，TN = 9.8 K.有效的磁矩合理地与MN2+的高旋转构型相吻合（s = 5/2）。构建了化合物。
Ion-exchange treatment of Na2SnTeO6 in molten salt mixtures resulted in rosiaite (PbSb2O6)-related MnSnTeO6. Its crystal structure was refined by the Rietveld method. Of the three possible models of Sn/Te distribution, the disordered model ((P3 Im, a = 5.23093(11) A, c = 4.62430(16) A was preferred based on bond distances. However, it is supposed that each individual (SnTeO6)2- layer retains complete ordering of the precursor and the apparent disorder is only due to stacking faults. The magnetic studies have shown that MnSnTeO6 orders antiferromagnetically at Neel temperature TN = 9.8 K. The effective magnetic moment reasonably agrees with theoretical estimations assuming high-spin configuration of Mn2+ (S = 5/2). Electron spin resonance reveals spin dynamics in accordance with aniferromagnetic ordering with critical broadening of ESR linewidth indicating the low-dimentional type of exchange interactions. Based on the temperature and field-dependent magnetization studies, the magnetic phase diagram of the new compound was constructed.
