摘要：

We report spectroscopic details of the excitation spectrum of the magnetic-field-induced spin-density-wave phases in the organic conductor (TMTSF)2ClO4 where TMTSF represents tetramethyl-tetraselenafulvalene. In contrast to theoretical predictions, the value of the energy gap is found to be constant in the different subphases, whereas the carrier density in the spin-density-wave state increases discontinuously upon each successive phase transition. In addition, we find evidence for a collective mode excitation in the microwave region, and a strong interaction of low-energy phonons with the spin-density-wave formation.
