Title: Structural and Magnetic Phase Transitions near Optimal Superconductivity in ${{BaFe}_{2} ({As}_{1 - x} P_{x})}_{2}$

Abstract

We use nuclear magnetic resonance (NMR), high-resolution x-ray, and neutron scattering studies to study structural and magnetic phase transitions in phosphorus-doped BaFe2(As1-xPx)(2). Previous transport, NMR, specific heat, and magnetic penetration depth measurements have provided compelling evidence for the presence of a quantum critical point (QCP) near optimal superconductivity at x = 0.3. However, we show that the tetragonal-to-orthorhombic structural (T-s) and paramagnetic to antiferromagnetic (AF, T-N) transitions in BaFe2(As1-xPx)(2) are always coupled and approach T-N approximate to T-s >= T-c (approximate to 29 K) for x = 0.29 before vanishing abruptly for x >= 0.3. These results suggest that AF order in BaFe2(As1-xPx)(2) disappears in a weakly first-order fashion near optimal superconductivity, much like the electron-doped iron pnictides with an avoided QCP.

Effect of proton irradiation on superconductivity in optimally doped ${BaFe}_{2} ({As}_{1 - x} P_{x})_{2}$ single crystals

Journal Article Smylie, M. P. ; Leroux, M. ; Mishra, V. ; ... - Physical Review B

Irradiation with 4-MeV protons was used to systematically introduce defects in single crystals of the iron- arsenide superconductor BaFe2(As1-xPx)2, x=0.33. The effect of disorder was investigated on the low temperature behavior of the London penetration depth, y(T) and transition temperature, Tc. In near-optimal doped samples with Tc ~ 29 K, signatures of gap with nodes were observed. Our results suggest that the nature of defects created by proton irradiation differs from electron irradiation. Contrary to other reports, we do not see a disorder driven lifting of accidental nodes, and we observe that proton induced defects are weaker pairbreakers than electronmore » induced defects.« less

Structural and magnetic phase transitions near optimal superconductivity in BaFe ₂(As _1-xP _x) ₂

In this study, we use nuclear magnetic resonance (NMR), high-resolution x-ray and neutron scattering to study structural and magnetic phase transitions in phosphorus-doped BaFe ₂(As _1-xP _x) ₂. Thus, previous transport, NMR, specific heat, and magnetic penetration depth measurements have provided compelling evidence for the presence of a quantum critical point (QCP) near optimal superconductivity at x = 0.3. However, we show that the tetragonal-to-orthorhombic structural (T _s) and paramagnetic to antiferromagnetic (AF, T _N) transitions in BaFe ₂(As _1-xP _x) ₂ are always coupled and approach to T _N ≈ T _s ≥ T _c (≈ 29 K) formore »« less

Unconventional Charge Density Wave Order in the Pnictide Superconductor $Ba ({Ni}_{1 - x} {Co}_{x})_{2} {As}_{2}$

Journal Article Lee, Sangjun ; de la Peña, Gilberto ; Sun, Stella X. -L. ; ... - Physical Review Letters

Ba(Ni _1–xCo _x) ₂As ₂ is a structural homologue of the pnictide high temperature superconductor, Ba(Fe _1–xCo _x) ₂As ₂, in which the Fe atoms are replaced by Ni. Superconductivity is highly suppressed in this system, reaching a maximum T_c = 2.3 K, compared to 24 K in its iron-based cousin, and the origin of this T_c suppression is not known. Using x-ray scattering, we show that Ba(Ni _1–xCo _x) ₂As ₂ exhibits a unidirectional charge density wave (CDW) at its triclinic phase transition. The CDW is incommensurate, exhibits a sizable lattice distortion, and is accompanied by the appearance ofmore »« less

Uniaxial pressure effect on the magnetic ordered moment and transition temperatures in ${BaFe}_{2 - x} T_{x} {As}_{2}$ ( $T = Co, Ni$ )

Journal Article Tam, David W. ; Song, Yu ; Man, Haoran ; ... - Physical Review B

In this paper, we use neutron diffraction and muon spin relaxation to study the effect of in-plane uniaxial pressure on the antiferromagnetic (AF) orthorhombic phase in BaFe ₂As ₂ and its Co- and Ni-substituted members near optimal superconductivity. In the low-temperature AF ordered state, uniaxial pressure necessary to detwin the orthorhombic crystals also increases the magnetic ordered moment, reaching an 11% increase under 40 MPa for BaFe _1.9Co _0.1As ₂, and a 15% increase for BaFe _1.915Ni _0.085As ₂. We also observe an increase of the AF ordering temperature (T _N) of about 0.25 K/MPa in all compounds, consistent withmore »« less

Hedgehog Spin-Vortex Crystal Antiferromagnetic Quantum Criticality in $CaK ({Fe}_{1 - x} {Ni}_{x})_{4} {As}_{4}$ Revealed by NMR

Journal Article Ding, Q. -P. ; Meier, W. R. ; Cui, J. ; ... - Physical Review Letters

Two ordering states, antiferromagnetism and nematicity, have been observed in most iron-based superconductors (SCs). In contrast to those SCs, the newly discovered SC CaK(Fe _1-xNi _x) ₄As ₄ exhibits an antiferromagnetic (AFM) state, called hedgehog spin-vortex crystal structure, without nematic order, providing the opportunity for the investigation into the relationship between spin fluctuations and SC without any effects of nematic fluctuations. Our ⁷⁵As nuclear magnetic resonance studies on CaK(Fe _1-xNi _x) ₄As ₄ (0≤ x ≤ 0.049) revealed that CaKFe ₄As ₄ is located close to a hidden hedgehog SVC AFM quantum-critical point (QCP). The magnetic QCP without nematicity inmore »« less
