The observation of bulk superconductivity in Rhombohedral ReO3 under pressure

S. Huyan, R. F. S. Penacchio, L-L. Wang +10

Understanding how lattice geometry enables superconductivity in oxides remains a central challenge. Here, we report a systematic study of ReO3 up to 80 GPa. Synchrotron X-ray diffr…

Trapped flux in a small crystal of CaKFe $_{4}$ As $_{4}$ at ambient pressure and in a diamond anvil pressure cell

Sergey L. Bud'ko, Shuyuan Huyan, Mingyu Xu +1

In an extension of our previous work, [Sergey L Bud'ko et al 2023 Supercond. Sci. Technol. 36 115001] the measurements of temperature dependent magnetization associated with trappe…

Pressure tuned superconductivity and normal state behavior in Ba(Fe $_{0.943}$ Co $_{0.057}$ ) $_{2}$ As $_{2}$ near the antiferromagnetic boundary

W. Liu, Y. F. Wu, X. J. Li +8

Superconductivity in iron pnictides is unconventional and pairing may be mediated by magnetic fluctuations in the Fe-sublattice. Pressure is a clean method to explore superconducti…

Detection of Orbital Fluctuations Above the Structural Transition Temperature in the Iron-Pnictides and Chalcogenides

H. Z. Arham, C. R. Hunt, W. K. Park +15

We use point contact spectroscopy to probe $AEF e_{2} A s_{2}$ ( $AE = Ca, Sr, Ba$ ) and $F e_{1 + y} Te$ . For $AE = Sr, Ba$ we detect orbital fluctuations above $T_{S}$ while for…

Upper critical magnetic field in Ba_0.68K_0.32Fe_2As_2 and Ba(Fe_0.93Co_0.07)_2As_2

V. A. Gasparov, L. Drigo, A. Audouard +6

We report measurements of the temperature dependence of the radio-frequency magnetic penetration depth in Ba_0.68K_0.32Fe_2As_2 and Ba(Fe_0.93Co_0.07)_2As_2 single crystals in puls…

Evidence from neutron diffraction for superconductivity in the stabilized tetragonal phase of CaFe2As2 under uniaxial pressure

K. Prokes, A. Kreyssig, B. Ouladdiaf +7

CaFe2As2 single crystals under uniaxial pressure applied along the c axis exhibit the coexistence of several structural phases at low temperatures. We show that the room-temperatur…

Magnetic Impurities in the Pnictide Superconductor Ba $_{1 - x}$ K $_{x}$ Fe $_{2}$ As $_{2}$

Sutirtha Mukhopadhyay, Sangwon Oh, A M Mounce +7

NMR measurements have been performed on single crystals of Ba $_{1 - x}$ K $_{x}$ Fe $_{2}$ As $_{2}$ (x = 0, 0.45) and CaFe $_{2}$ As $_{2}$ grown from Sn flux. The Ba-based pnictide crystals contain…
