Title: Competition between orthorhombic and re-entrant tetragonal phases in underdoped Ba_1–xK_xFe₂As₂ probed by the response to controlled disorder

Abstract

Low-temperature (22 K) irradiation with 2.5-MeV electrons, creating point defects affecting elastic scattering, was used to study the competition between stripe C₂ and tetragonal C₄ antiferromagnetic phases which exist in a narrow doping range around x = 0.25 in hole-doped Ba_1–xK_xFe₂As₂. In nearby compositions outside of this range, at x = 0.22 and x = 0.19, the temperatures of both the concomitant orthorhombic/stripe antiferromagnetic transition T_C2 and the superconducting transition T_c are monotonically suppressed by added disorder at similar rates of about 0.1 K/μΩcm, as revealed through using resistivity variation as an intrinsic measure of scattering rate. In a stark contrast, a rapid suppression of the C₄ phase at the rate of 0.24 K/μΩcm is found at x = 0.25. Moreover, this suppression of the C₄ phase is accompanied by unusual disorder-induced stabilization of the C₂ phase, determined by resistivity and specific heat measurements. Furthermore, the rate of the C₄ phase suppression is notably higher than the suppression rate of the spin-vortex phase in the Ni-doped CaKFe₄As₄ (0.16 K/μΩcm).

Competition between orthorhombic and re-entrant tetragonal phases in underdoped ${Ba}_{1 - x} K_{x} {Fe}_{2} {As}_{2}$ probed by the response to controlled disorder

XAFS study of the low-temperature tetragonal phase of La{sub 2-x}Ba{sub x}CuO{sub 4}: Disorder, stripes, and T{sub c} suppression at x=0.125

Journal Article Haskel, D ; Stern, E A ; Dogan, F ; ... - Physical Review. B, Condensed Matter and Materials Physics

Angular dependent x-ray absorption fine structure (XAFS) measurements of all La, Ba, and Cu sites determined the origin and nature of the intrinsic disorder present in the low temperature tetragonal (LTT) structural ground state of La{sub 2-x}Ba{sub x}CuO{sub 4} with x=0.125,0.15 at T=10 K. Ba doping induces major local distortions that extend as far as 5 Aa from its lattice site. Despite the low Ba content the large distortions significantly affect the XAFS of the majority La and Cu sites. The distribution of the local LTT tilt angle of CuO{sub 6} octahedra was directly determined from single and multiple scatteringmore »« less

Interplay between superconductivity and itinerant magnetism in underdoped Ba_1–xK_xFe₂As₂ (x = 0.2) probed by the response to controlled point-like disorder

Journal Article Prozorov, Ruslan ; Kończykowski, Marcin ; Tanatar, Makariy A. ; ... - npj Quantum Materials

The response of superconductors to controlled introduction of point-like disorder is an important tool to probe their microscopic electronic collective behavior. In the case of iron-based superconductors, magnetic fluctuations presumably play an important role in inducing high-temperature superconductivity. In some cases, these two seemingly incompatible orders coexist microscopically. Therefore, understanding how this unique coexistence state is affected by disorder can provide important information about the microscopic mechanisms involved. In one of the most studied pnictide family, hole-doped Ba_1–xK_xFe₂As₂ (BaK122), this coexistence occurs over a wide range of doping levels, 0.16 ≲ x ≲ 0.25. We used relativistic 2.5 MeV electronsmore »« less

Phase diagram of Ba{sub 1-x}K{sub x}Fe{sub 2}As{sub 2}.

Journal Article Avci, S ; Chmaissem, O ; Chung, D Y ; ... - Physical Review. B, Condensed Matter and Materials Physics

We report the results of a systematic investigation of the phase diagram of the iron-based superconductor Ba{sub 1-x}K{sub x}Fe{sub 2}As{sub 2} from x = 0 to x = 1.0 using high-resolution neutron and x-ray diffraction and magnetization measurements. The polycrystalline samples were prepared with an estimated compositional variation of {Delta}x {le} 0.01, allowing a more precise estimate of the phase boundaries than reported so far. At room temperature, Ba{sub 1-x}K{sub x}Fe{sub 2}As{sub 2} crystallizes in a tetragonal structure with the space group symmetry of I4/mmm, but at low doping, the samples undergo a coincident first-order structural and magnetic phase transitionmore »« less

Non-Fermi-liquid types of behavior associated with a magnetic quantum critical point in $Sr {({Co}_{1 - x} {Ni}_{x})}_{2} {As}_{2}$ single crystals

Journal Article Sangeetha, N. S. ; Wang, L. -L. ; Smirnov, A. V. ; ... - Physical Review B

The compound SrCo₂As₂ with the body-centered tetragonal ThCr₂Si₂ structure is known to remain paramagnetic down to a temperature T = 0.05 K, but inelastic neutron scattering studies have shown that both ferromagnetic (FM) and antiferromagnetic (AFM) fluctuations occur in single crystals. Thus it is of interest to study how the magnetism evolves on doping SrCo₂As₂. Previous work on polycrystalline samples of Sr (Co_1-x Ni_x)₂ As₂ indicated the development of AFM order for 0 < x ≲ 0.3. Here we studied single crystals of Sr(Co_1-x Ni_x)₂ As₂ for 0 < x ≤ 1 and confirmed the occurrence of AFM order whichmore »« less
