On single crystal total scattering data reduction and correction protocols for analysis in direct space
Robert J. Koch, Nikolaj Roth, Yiu Liu +6
We explore data reduction and correction steps and processed data reproducibility in the emerging single crystal total scattering based technique of three-dimensional differential…
Evidence of superconductivity-induced phonon spectra renormalization in alkali-doped iron selenides
M. Opačić, N. Lazarević, M. Šćepanović +4
Polarized Raman scattering spectra of superconducting KFeSe and nonsuperconducting KFeCoSe single crystals were measured in a temperatur…
Raman spectroscopy of K_xCo_{2-y}Se_2 single crystals near the ferromagnet-paramagnet transition
M. Opačić, N. Lazarević, M. M. Radonjić +6
Polarized Raman scattering spectra of the K_xCo_{2-y}Se_2 single crystals reveal the presence of two phonon modes, assigned as of the A_{1g} and B_{1g} symmetry. Absence of additio…
Magnetic excitations in the spin-1/2 triangular-lattice antiferromagnet CsCuBr
S. A. Zvyagin, M. Ozerov, D. Kamenskyi +8
We report on high-field electron spin resonance (ESR) studies of magnetic excitations in the spin-1/2 triangular-lattice antiferromagnet CsCuBr. Frequency-field diagrams of…
Physical properties of KxNi2-ySe2 single crystals
Hechang Lei, Kefeng Wang, Hyejin Ryu +3
We have synthesized K0.95(1)Ni1.86(2)Se2 single crystals. The single crystals contain K and Ni deficiencies not observed in KNi2Se2 polycrystals. Unlike KNi2Se2 polycrystals, the s…
Local structural disorder and superconductivity in KxFe2-ySe2
Hyejin Ryu, Hechang Lei, A. I. Frenkel +1
We report significantly enhanced magnetic moment in K0.69(2)Fe1.45(1)Se2.00(1) single crystals with sharp Tc and bulk superconductivity obtained by postannealing and quenching proc…
NMR Characterization of Sulphur Substitution Effects in the K(x)Fe(2-y)Se(2-z)S(z) high Tc Superconductor
D. A. Torchetti, T. Imai, H. C. Lei +1
We present an NMR study of the effect of S substitution in the high Tc superconductor K(x)Fe(2-y)Se(2-z)S(z) in a temperature range up to 250 K. We present NMR Knight shift and nuc…
Heat transport as a probe of superconducting gap structure
H Shakeripour, C Petrovic, Louis Taillefer
The structure of the superconducting gap provides important clues on the symmetry of the order parameter and the pairing mechanism. The presence of nodes in the gap function impose…
