我们研究了通过控制层间距来改变过渡金属三硫化磷MnPS_3的磁性，层间距通过插入和施加高压来改变。通过在373 K下搅拌8小时，实现了吡啶到MnPS 3中的完美插层。该插层相（P1.9）的层间距d是MnPS 3的1.9倍。此外，得到了一种新的插层相（P2.7），其中d是MnPS 3的2.7倍。后一相不稳定，并在空气中放置约10分钟后转变为新相（P2.0），其d值是MnPS 3的2.0倍。P1.9的磁化强度与温度的关系显示亚铁磁性，居里温度TC为40 K，而MnPS 3是反铁磁体，Neel温度TN为78 K。高压X射线衍射测量表明，层间分离随着压力的增加而迅速减小（约1%/GPa）。这一点可以从Wea...
We have investigated the change of magnetism of the transition metal phosphorous trisulfide MnPS3 by controlling the interlayer distance, which was varied by intercalation and by applying high pressure. A perfect pyridine intercalation into MnPS3 was achieved by stirring at 373 K for 8 hours. The interlayer distance d of this intercalated phase (P1.9) is 1.9 times lager than that of MnPS3. Furthermore, a new intercalated phase (P2.7), where d is 2.7 times larger than that of MnPS3, was obtained. The latter phase is unstable and changed to a new phase (P2.0) with a d value which is 2.0 times larger than that of MnPS3 by leaving it in air for about 10 minutes. The temperature dependence of the magnetization of P1.9 shows ferrimagnetism with a Curie temperature TC of 40 K, while MnPS3 is an antiferromagnet with a Neel temperature TN of 78 K. High pressure X‐ray diffraction measurements show that the interlayer separation decreases rapidly with increasing pressure (∼ 1%/GPa). This is explained well by the wea...
