Disorder raises the critical temperature of a cuprate superconductor
Maxime Leroux, Vivek Mishra, Jacob P. C. Ruff +10
With the discovery of charge density waves (CDW) in most members of the cuprate high temperature superconductors, the interplay between superconductivity and CDW has become a key p…
Heat capacity jump at T_c and pressure derivatives of superconducting transition temperature in the Ba(1-x)NaxFe2As2 (0.1 <= x <= 0.9) series
Sergey L. Bud'ko, Duck Young Chung, Daniel Bugaris +3
We present the evolution of the initial (up to ~ 10 kbar) hydrostatic, pressure dependencies of T_c and of the ambient pressure jump in the heat capacity associated with the superc…
Tetragonal magnetic phase in BaKFeAs from x-ray and neutron diffraction
Jared M. Allred, Sevda Avci, Duck Young Chung +8
Combined neutron and x-ray diffraction experiments demonstrate the formation of a low-temperature minority tetragonal phase in BaKFeAs in addition to the…
The cuprate phase diagram and the influence of nanoscale inhomogeneities
Nader Zaki, Hongbo Yang, Jon Rameau +3
The phase diagram associated with the high Tc superconductors is complicated by an array of different ground states. The parent material represents an antiferromagnetic insulator b…
Phase relations in K_xFe_{2-y}Se_2 and the structure of superconducting K_xFe_2Se_2 via high-resolution synchrotron diffraction
Daniel P. Shoemaker, Duck Young Chung, Helmut Claus +4
Superconductivity in iron selenides has experienced a rapid growth, but not without major inconsistencies in the reported properties. For alkali-intercalated iron selenides, even t…
Phase Diagram of Ba1-xKxFe2As2
Sevda Avci, Omar Chmaissem, Duck-Young Chung +10
We report the results of a systematic investigation of the phase diagram of the iron-based superconductor, Ba1-xKxFe2As2, from x = 0 to x = 1.0 using high resolution neutron and x-…
