Title: Expansion of the tetragonal magnetic phase with pressure in the iron arsenide superconductor ${Ba}_{1 - x} K_{x} {Fe}_{2} {As}_{2}$

Abstract

In the temperature-concentration phase diagram of most iron-based superconductors, antiferromagnetic order is gradually suppressed to zero at a critical point, and a dome of superconductivity forms around that point. The nature of the magnetic phase and its fluctuations is of fundamental importance for elucidating the pairing mechanism. In Ba_1–xK_xFe₂As₂ and Ba_1–xNa_xFe₂As₂, it has recently become clear that the usual stripelike magnetic phase, of orthorhombic symmetry, gives way to a second magnetic phase, of tetragonal symmetry, near the critical point, in the range from x = 0.24 to x = 0.28 for Ba_1–xK_xFe₂As₂. In a prior study, an unidentified phase was discovered for x < 0.24 but under applied pressure, whose onset was detected as a sharp anomaly in the resistivity. Here we report measurements of the electrical resistivity of Ba_1–xK_xFe₂As₂ under applied hydrostatic pressures up to 2.75 GPa, for x = 0.22, 0.24, and 0.28. The critical pressure above which the unidentified phase appears is seen to decrease with increasing x and vanish at x = 0.24, thereby linking the pressure-induced phase to the tetragonal magnetic phase observed at ambient pressure. In the temperature-concentration phase diagram of Ba_1–xK_xFe₂As₂, we find that pressure greatly expands the tetragonal magnetic phase, while themore »« less

Symmetry of reentrant tetragonal phase in ${Ba}_{1 - x} {Na}_{x} {Fe}_{2} {As}_{2}$ : Magnetic versus orbital ordering mechanism

Journal Article Khalyavin, D. D. ; Lovesey, S. W. ; Manuel, P. ; ... - Physical Review. B, Condensed Matter and Materials Physics

Magnetostructural phase transitions in Ba_1-xA_xFe₂As₂ (A = K, Na) materials are discussed for both magnetically and orbitally driven mechanisms, using a symmetry analysis formulated within the Landau theory of phase transitions. Both mechanisms predict identical orthorhombic space-group symmetries for the nematic and magnetic phases observed over much of the phase diagram, but they predict different tetragonal space-group symmetries for the newly discovered reentrant tetragonal phase in Ba_1-xNa_xFe₂As₂ (x similar to 0.24-0.28). In a magnetic scenario, magnetic order with moments along the c axis, as found experimentally, does not allow any type of orbital order, but in an orbital scenario, wemore »« less

Journal Article Allred, J. M. ; Avci, S. ; Chung, D. Y. ; ... - Physical Review. B, Condensed Matter and Materials Physics

In this paper, combined neutron and x-ray diffraction experiments demonstrate the formation of a low-temperature minority magnetic tetragonal phase in Ba_0.76K_0.24Fe₂As₂ in addition to the majority magnetic, orthorhombic phase. The coincident enhancement in the magnetic (1/2 1/2 1) peaks shows that this minority phase is of the same type that was observed in Ba_1-xNa_xFe₂As₂ (0.24 ≤ x ≤ 0.28), in which the magnetic moments reorient along the c axis. This is evidence that the tetragonal magnetic phase is a universal feature of the hole-doped iron-based superconductors. Finally, the observations suggest that in this regime the energy levels of the C₂more »« less

Heat capacity jump at $T_{c}$ and pressure derivatives of superconducting transition temperature in the Ba $_{1 - x}$ Na $_{x}$ Fe $_{2}$ As $_{2}$ ( $0.1 \leq x \leq 0.9$ ) series

Journal Article Bud'ko, Sergey L. ; Chung, Duck Young ; Bugaris, Daniel ; ... - Physical Review. B, Condensed Matter and Materials Physics

We present the evolution of the initial (up to ~ 10 kbar) hydrostatic pressure dependencies of T_c and of the ambient pressure, and the jump in the heat capacity associated with the superconducting transition as a function of Na doping in the Ba1-xNaxFe2As2 family of iron-based superconductors. For Na concentrations 0.15 ≤ x ≤ 0.9, the jump in specific heat at T_c, ΔC_p|_{Tmore » $$_c$$}, follows the ΔC_p ∝ to T³ (the so-called BNC scaling) found for most BaFe₂As₂ based superconductors. This finding suggests that, unlike the related Ba_1-xK_xFe₂As₂ series, there is no significant modification of the superconducting state (e. g., change in superconducting gap symmetry) in the Ba_1-xNa_xFe₂As₂ series over the whole studied Na concentration range. Pressure dependencies are nonmonotonic for x = 0.2 and 0.24. For other Na concentrations, T_c decreases under pressure in an almost linear fashion. The anomalous behavior of the x = 0.2 and 0.24 samples under pressure is possibly due to the crossing of the phase boundaries of the narrow antiferromagnetic tetragonal phase, unique for the Ba_1-xNa_xFe₂As₂ series, with the application of pressure. The negative sign of the pressure derivatives of T_c across the whole superconducting dome (except for x = 0.2) is a clear indication of the nonequivalence of substitution and pressure for the Ba_1-xNa_xFe₂As₂ series.« less

Observation of the magnetic $C_{4}$ phase in ${Ca}_{1 - x} {Na}_{x} {Fe}_{2} {As}_{2}$ and its universality in the hole-doped 122 superconductors

Journal Article Taddei, K. M. ; Allred, J. M. ; Bugaris, D. E. ; ... - Physical Review B

Since its discovery in 2014, the magnetic tetragonal C₄ phase has been identified in a growing number of hole-doped 122 Fe-based superconducting compounds. Exhibiting a unique double-Q magnetic structure and a strong competition with both superconducting and magnetic order parameters, the C₄ phase and the conditions of its formation are of significant interest to understanding the fundamental mechanisms in these materials. Particularly, separating the importance of direct changes to the relative size of hole and electron pockets at the Fermi surface (achieved via charge doping) from the role of structural changes due to differences of ionic radii of dopants ismore »« less

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

Journal Article Timmons, E. I. ; Tanatar, M. A. ; Willa, K. ; ... - Physical Review B

Low-temperature (22 K) irradiation with 2.5-MeV electrons, creating point defects affecting elastic scattering, was used to study the competition between stripe C-2 and tetragonal C-4 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/mu Ω cm, as revealed through using resistivity variation as an intrinsic measure of scattering rate.
