将Gor 'kov和Lebed方法扩展到更一般的自旋密度波（SDW）矢量，从理论上研究了Bechgaard盐场致自旋密度波的热力学。确定了SDW中的准粒子谱。热力学和BCS超导体是一样的。我们预测了SDW在磁场中的级联跃迁，这很好地描述了观察到的松弛的四甲基四烯丙烯高氯酸盐[(TMTSF) 2 clo4]的相图。我们还计算了SDW的磁化强度，它再次很好地描述了（TMTSF） 2clo4的磁化强度。
Extending the Gor’kov and Lebed approach to more general spin-density-wave (SDW) vectors, we study theoretically the thermodynamics of the field-induced SDW in Bechgaard salts. The quasiparticle spectrum in the SDW is determined. The thermodynamics is identical to that for a BCS superconductor. We predict a cascade of SDW transitions in magnetic fields, which describes the observed phase diagram of the relaxed bis (tetramethyltetraselenafulvalene) perchlorate [(TMTSF) 2 ClO 4] extremely well. We calculate also the magnetization in SDW, which again describes the observed magnetization in (TMTSF) 2 ClO 4 quite well.
