Role of Local Ru Hexamers in Superconductivity of Ruthenium Phosphide
Robert J. Koch, Niraj Aryal, Oleh Ivashko +7
Superconductivity in binary ruthenium pnictides occurs proximal to and upon suppression of a mysterious non-magnetic ground state, preceded by a pseudogap phase associated with Fer…
Photoinduced ultrafast dynamics of local nematicity and lattice distortions in FeSe crystals
T. Konstantinova, L. Wu, M. Abeykoon +12
Formation of electronic nematicity is a common thread of unconventional superconductors. In iron-based materials, the long-range nematic order is revealed by the orthorhombic latti…
Insulating and metallic spin glass in KFeNiSe (0.06 1.44) single crystals
Hyejin Ryu, Milinda Abeykoon, Kefeng Wang +6
We report electron doping effects by Ni in KFeNiSe (0.06 1.44) single crystal alloys. A rich ground state phase diagram is observed. S…
Superconductivity in Ir1-xRhxTe2 (0<=x<=0.3)
Hechang Lei, Kefeng Wang, Milinda Abeykoon +3
We report superconductivity, physical and structural properties of Ir1-xRhxTe2 (0<=x<=0.3). Superconducting transition with maximum Tc~2.6 K appears when the doping content of Rh x…
New layered fluorosulfide SrFBiS2
Hechang Lei, Kefeng Wang, Milinda Abeykoon +2
We have synthesized a new layered BiS-based compound SrFBiS2. This compound has similar structure to BiS2. It is built up by stacking up SrF layers and NaCl-type BiS2 layers…
Synthesis, crystal structure and magnetism of beta-Fe1.00(2)Se1.00(3) single crystals
Rongwei Hu, Hechang Lei, Milinda Abeykoon +5
Understanding iron based superconductors requires high quality impurity free single crystals. So far they have been elusive for beta-FeSe and extraction of intrinsic materials prop…
Phase Diagram of KxFe2-ySe2-zSz and the Suppression of its Superconducting State by an Fe2-Se/S Tetrahedron Distortion
Hechang Lei, Milinda Abeykoon, Emil S. Bozin +3
We report structurally tuned superconductivity in KxFe2-ySe2-zSz (0<=z<=2) phase diagram. Superconducting Tc is suppressed as S is incorporated into the lattice, eventually vanishi…
Spin glass behavior of insulating K0.8Fe2-xS2
Hechang Lei, Milinda Abeykoon, Emil S. Bozin +1
We report the discovery of KxFe2-yS2 single crystals, isostructural to KxFe2-ySe2 superconductors. The sulfide compound is a small gap semiconductor and shows spin-glass behavior b…
