Pressure effects on superconducting properties of single-crystalline Co doped NaFeAs

A. F. Wang, Z. J. Xiang, J. J. Ying +5

Resistivity and magnetic susceptibility measurements under external pressure were performed on single-crystals NaFe1-xCoxAs (x=0, 0.01, 0.028, 0.075, 0.109). The maximum Tc enhance…

A crossover in phase diagram of NaFeCoAs determined by electronic transport measurements

A. F. Wang, J. J. Ying, X. G. Luo +8

We report electronic transport measurements on single crystals of NaFeCoAs system. We found that the cotangent of Hall angle, cot, follows for the pare…

Angle-resolved photoemission evidence of s-wave superconducting gap in KxFe2-ySe2 superconductor

M. Xu, Q. Q. Ge, R. Peng +7

Although nodeless superconducting gap has been observed on the large Fermi pockets around the zone corner in KxFe2-ySe2, whether its pairing symmetry is s-wave or nodeless d-wave i…

Phase Diagram and Calorimetric Properties of NaFeCoAs

A. F. Wang, X. G. Luo, Y. J. Yan +7

We measured the resistivity and magnetic susceptibility to map out the phase diagram of single crystalline NaFeCoAs. Replacement of Fe by Co suppresses both the structu…

Evolution from unconventional spin density wave to superconductivity and a novel gap-like phase in NaFe1-xCoxAs

Xiaodong Zhou, Peng Cai, Aifeng Wang +6

Similar to the cuprate high TC superconductors, the iron pnictide superconductors also lie in close proximity to a magnetically ordered phase. A central debate concerning the super…

Transport Properties and Electronic Phase Diagram of Single-Crystalline Ca(PtAs) ((FePt)As)

Z. J. Xiang, X. G. Luo, J. J. Ying +6

Sizable single-crystalline samples of Ca(PtAs)((FePt)As) (the 10-3-8 phase) with 00.1 have been grown and systematically characteriz…
