We report the discovery of superconductivity at high pressure in SrFe 2 As 2 and BaFe 2 As
2. The superconducting transition temperatures are up to 27 K in SrFe 2 As 2 and 29 K in …

Abstract (Tl, K) Fe x Se 2 single crystals were first successfully synthesized with the
Bridgeman method. The physical properties are characterized by electrical resistivity …

CaFe 2 As 2 has been synthesized and found to form in the tetragonal ThCr 2 Si 2 structure
with lattice parameters a= 3.912 (68) Å and c= 11.667 (45) Å. Upon cooling through 170 K …

In this review, we present a summary of experimental studies of magnetism in Fe-based
superconductors. The doping dependent phase diagram shows strong similarities to the …

We apply the fermion functional renormalization-group method to determine the pairing
symmetry and pairing mechanism of the FeAs-Based materials. Within a five band model …

The parent phases of the Fe-arsenide superconductors harbor an antiferromagnetic ground
state. Significantly, the Néel transition is either preceded or accompanied by a structural …

Neutron diffraction measurements of a high-quality single crystal of CaFe 2 As 2 are
reported. A sharp transition was observed between the high-temperature tetragonal and low …
