摘要：
We investigated the magnetization of the organic weak-ferromagnet p-NC.C6F4.CNSSN in the pressure P region up to 16 kbar. The transition temperature T-c at ambient pressure is 35.5 K. T-c is enhanced with increasing pressure, and reaches 64.5K at P = 16 kbar, which is the highest T-c for a genuine organic weak-ferromagnet. On the other hand, the net moment is suppressed by the pressure, and this call be explained with the Dzyaloshinsky-Moriya model. (C) 2001 Elsevier Science Ltd. All rights reserved.
