We study temperature dependent upper critical field H<SUB>c2</SUB> of a SrFe<SUB>1.85</SUB>Co<SUB>0.15</SUB>As<SUB>2</SUB> single crystal (T<SUB>c</SUB>=20.2K) along ab-plane and c-axis through resistivity measurements up to 50T. For the both crystalline directions, H<SUB>c2</SUB> becomes nearly isotropic at zero temperature limit, reaching ~48T. The temperature dependence of the H<SUB>c2</SUB> curves is explained by interplay between orbital and Pauli limiting behaviors combined with the two band effects.
Robust Magnetic Order of Ce 4f-electrons Coexisting with Superconductivity in CeFeAsO1−xFx
T. Shang,L. Jiao,J. Dai,H. Q. Yuan,F. F. Balakirev,W. Z. Hu,N. L. Wang 한국물리학회 2013 THE JOURNAL OF THE KOREAN PHYSICAL SOCIETY Vol.62 No.12
The electrical resistance of CeFeAsO1−xFx (x = 0.06 and 0.08) has been measured in magneticfields up to 40 T. At zero field, the sample with x = 0.06 shows a structural phase transition aroundTS 100 K, followed by a spin-density-wave (SDW) transition around TSDW 30 K. For x =0.08, the structural phase transition is suppressed down to TS 60 K without a clear anomalyassociated with the Fe-SDW transition, and superconductivity shows up at TC 25 K. At lowertemperatures, both samples show a clear resistive peak around TN 4 K, which is associated withthe antiferromagnetic (AFM) transition of Ce 4f-electrons. Strikingly, zero resistance is recoveredupon a further lowering of the temperature to below TN for x = 0.08. Moreover, we found thatthe AFM transition of Ce 4f-electrons at 4 K hardly change when a magnetic field of up to 40 Twas applied. This was true even in the case of x = 0.08, for which the superconductivity had beenpartially suppressed at such a large field.
