The X-ray Study of the Field Induced Spin Density Wave State in TMTSF based

在这三年里，我们收到了以下结果：1.在高磁场中的低温X射线测量已经进行了性能。DMET-TSeF系统中的新实验结果与TMTSF已经获得的相似之处。特别是，国际合作已经完成了在高领域的测量。理论调查已经对TMTSF系统的高场阶段的FISDW状态进行了分析，该状态使用了一种扩展的标准理论来证明阴离子潜力，目前的一些工作已经出版，especially on the experimental techniques which are inevitable in our study.We have found peculiar and characteristic properties in the FISDW states of DMET-TSeF based compounds which are（DMET-TSeF）D22 AuCL D22 and （DMET-TSeF）D22 AuI D22。研究表明，使用混合磁铁在高场地区的霍尔效应在彼此之间完全不同。结果表明，FISDW状态的滑动效应对DMET-TSeF系统的影响比TMTSF系统的影响更大。

In these 3 years, we have obtained following results.1. The low temperature X-ray measurements in the high magnetic fields have been performed.2. New experimental results in DMET-TSeF system which is similar to the TMTSF have been obtained. Especially, the international collaborations have been accomplished in the high field measurements.3. Theoretical investigations have been performed on the high field phase of the FISDW state of TMTSF systems using an extended standard theory considering anion potentials.A few of the present works have been already published, especially on the experimental techniques which are inevitable in our study.We have found peculiar and characteristic properties in the FISDW states of DMET-TSeF based compounds which are (DMET-TSeF)ィイD22ィエD2AuCLィイD22ィエD2 and (DMET-TSeF) ィイD22ィエD2AuIィイD22ィエD2. The results on the Hall effect in the high field regime using hybrid-magnets are completely different among each other. The results indicate that the sliding effect in the FISDW state is more important in the DMET-TSeF system than in the TMTSF system.
