中文摘要 | The electrical resistance of CeFeAsO1-x F (x) (x = 0.06 and 0.08) has been measured in magnetic fields up to 40 T. At zero field, the sample with x = 0.06 shows a structural phase transition around T (S) a parts per thousand 100 K, followed by a spin-density-wave (SDW) transition around T (SDW) a parts per thousand 30 K. For x = 0.08, the structural phase transition is suppressed down to T (S) a parts per thousand 60 K without a clear anomaly associated with the Fe-SDW transition, and superconductivity shows up at T (C) a parts per thousand 25 K. At lower temperatures, both samples show a clear resistive peak around T (N) a parts per thousand 4 K, which is associated with the antiferromagnetic (AFM) transition of Ce 4f-electrons. Strikingly, zero resistance is recovered upon a further lowering of the temperature to below T (N) for x = 0.08. Moreover, we found that the AFM transition of Ce 4f-electrons at 4 K hardly change when a magnetic field of up to 40 T was applied. This was true even in the case of x = 0.08, for which the superconductivity had been partially suppressed at such a large field. |
