摘要
alpha-(ET)(2) salts split into two groups: one superconducting and another with mysterious low temperature phase (LTP). The LTP does not exhibit X-ray signiture of conventional CDW or magnetic one for SDW. But the magnetic phase diagram suggests strongly a kind of CDW. We have analysed the threshold electric field of unconventional CDW (UCDW) both for H = 0 and H not equal 0. The threshold electric field for UCDW with H = 0 and for 3D weak-pinning limit describes reasonably well the one determined in alpha-(ET)(2)KHg(SCH)(4). The result for H not equal 0 is also presented. We propose that the LTP in alpha-(ET)(2) salts is most likely UCDW. (C) 2001 Elsevier Science B.V. All rights reserved.
