| 摘 要： | 合成了一个无机,有机纳米复合物(MPYNN)0.14Mn0.93PS3,即有机氮氧自由基MPYNN(N-甲基吡啶阳离子自由基)的MnPS3夹层化合物.通过X-射线粉末衍射和红外光谱等对其结构进行了表征,根据其0.56 nm的层间距扩大值推测夹层化合物中的客体分子在层间采取了分子平面近乎垂直于主体层的排列方式.通过SQUID测试了所得到的夹层化合物的磁性,结果表明夹层化合物(MPYNN)0.14Mn0.93PS3在10 K以上具有顺磁特性,而在7 K时出现了一个明显的磁相变,表现出自发磁化. |

| Abstract: | The synthesis and magnetism of an intercalation compound were studied based on 2-(4'-N-methylpyridinium)-4,4,5,5-tetramethyl-imidazolinyl-1-oxyl-3-oxide (Methylpyfidinium nitronyl nitroxide, MPYNN) radical into layered MnPS3.The lattice expansion of 0.56 nm suggests that the guest molecule plane of pyridine in MPYNN is arranged almost perpendicular to the host layer.Magnetic measurements by SQUID indicates that the intercalation compound of (MPYNN)0.14Mn0.93PS3 exhibits paramagnetism above 10 K, and then spontaneous magnetization occurs at 7K. |
