TMTSF pressure-temperature phase diagram

Fig- 2,9. Experimentally determined pressure-field-temperature phase diagrams for (a) (TMTSF)2PF6 and (b) (TMTSF)2C104. From [89]... 

Fig. 10.5 (TMTSF)2PF6 a phase diagram for the transition temperature as a function of the applied pressure. The data points are due to different authors. At low temperatures and low applied pressures, one observes the behaviour of an insulator with spin-density waves. At low temperature and high pressure, the substance is superconducting at higher temperature it is metallic. Crystallographic data triclinic, a = 7.29 A, b = 7J A,c= 13.52 A, = 83.39°, = 86.27°,... 

Figure 12.6 shows what is understood about the temperature-pressure phase diagram of several TMTSF salts.

TMTCF denotes TMTTF or TMTSF molecule. The amount of charge transfer in this family with one-dimensional structures is such TMTCF " and X . The band structure and the Fermi surface are open as shown in Fig. 29 for the case of (TMTTF)2X [94]. The phase diagram of this family on the plane of pressure (p) and temperature (7) is shown in Fig. 30 proposed by Jerome [95]. The major... 

The temperature dependence of resistivities of five typical DMET salts is shown in Fig. 1 [8]. Among them, three show superconductivity. (DMET)2Au(CN)2 shows a resistivity upturn at 28 K at ambient pressure, and needs some pressure to become a superconductor [2]. The insulating phase is SDW [9,10] and the T-P phase diagram (Fig. 2) [11] is similar to that of the (TMTSF)2X salts. However, the pressure range, where both superconductivity and...
