Evolution of nematic fluctuations in CaK(FeNi)As with spin-vortex crystal magnetic order
Anna E. Böhmer, Fei Chen, William R. Meier +11
The CaK(FeNi)As superconductors resemble the archetypal 122-type iron-based materials but have a crystal structure with distinctly lower symmetry. This fa…
Zero Energy States at a Normal--Cuprate-Superconductor Interface Probed by Shot Noise
O. Negri, M Zaberchik, A. Keren +1
We report measurements of the current noise generated by the optimally doped, x=0.15, junctions. For high transmission junctions on (110) surface, we…

Using angle-resolved photoemission spectroscopy it is revealed that in the vicinity of optimal doping the electronic structure of La2-xSrxCuO4 cuprate undergoes an electronic recon…
Collapsed Tetragonal Phase Transition in LaRuP
Gil Drachuck, Aashish Sapkota, Wageesha Jayasekara +5
The structural properties of LaRuP under external pressure have been studied up to 14 GPa, employing high-energy x-ray diffraction in a diamond-anvil pressure cell. At ambi…
Effect of biaxial strain on the phase transitions of Ca(Fe1-xCox)2As2
A. E. Böhmer, A. Sapkota, A. Kreyssig +5
We study the effect of applied strain as a physical control parameter for the phase transitions of Ca(Fe1-xCox)2As2 using resistivity, magnetization, x-ray diffraction and 57Fe Mös…

Single crystalline, single phase CaKFeAs has been grown out of a high temperature, quaternary melt. Temperature dependent measurements of x-ray diffraction, anisotropic…
Origin of the Resistivity Anisotropy in the Nematic Phase of FeSe
M. A. Tanatar, A. E. Böhmer, E. I. Timmons +7
The in-plane resistivity anisotropy is studied in strain-detwinned single crystals of FeSe. In contrast to other iron-based superconductors, FeSe does not develop long-range magnet…
