Title: Structural and magnetic phase transitions near optimal superconductivity in BaFe₂(As_1-xP_x)₂

Abstract

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 BaFe₂(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 BaFe₂(As_1-xP_x)₂ are always coupled and approach to T_N ≈ T_s ≥ T_c (≈ 29 K) for x = 0.29 before vanishing abruptly for x ≥ 0.3. These results suggest that AF order in BaFe₂(As_1-xP_x)₂ disappears in a weakly first order fashion near optimal superconductivity, much like the electron-doped iron pnictides with an avoided QCP.

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

Journal Article Hu, Ding ; Lu, Xingye ; Zhang, Wenliang ; ... - Physical Review Letters

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.

Nematic Fluctuations in the Non-Superconducting Iron Pnictide BaFe_1.9-xNi_0.1Cr_xAs₂

Journal Article Gong, Dongliang ; Yi, Ming ; Wang, Meng ; ... - Frontiers in Physics

The main driven force of the electronic nematic phase in iron-based superconductors is still under debate. Here, we report a comprehensive study on the nematic fluctuations in a non-superconducting iron pnictide system BaFe_1.9-xNi_0.1Cr_xAs₂ by electronic transport, angle-resolved photoemission spectroscopy (ARPES), and inelastic neutron scattering (INS) measurements. Previous neutron diffraction and transport measurements suggested that the collinear antiferromagnetism persists to x = 0.8, with similar Néel temperature TN and structural transition temperature Ts around 32 K, but the charge carriers change from electron type to hole type around x = 0.5. In this study, we have found that the in-plane resistivitymore »« less

Selective mass enhancement close to the quantum critical point in BaFe₂(As_1-xP_x)₂

Journal Article Grinenko, V. ; Iida, K. ; Kurth, F. ; ... - Scientific Reports

A quantum critical point (QCP) is currently being conjectured for the BaFe₂(As_1-xP_x)₂ system at the critical value x_c ≈ 0.3. In the proximity of a QCP, all thermodynamic and transport properties are expected to scale with a single characteristic energy, given by the quantum fluctuations. Such a universal behavior has not, however, been found in the superconducting upper critical field H_c2. Here we report H_c2 data for epitaxial thin films extracted from the electrical resistance measured in very high magnetic fields up to 67 Tesla. Using a multi-band analysis we find that H_c2 is sensitive to the QCP, implying amore »« 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 BaFe₂As₂ 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_0.1As₂, and a 15% increase for BaFe_1.915Ni_0.085As₂. We also observe an increase of the AF ordering temperature (T_N) of about 0.25 K/MPa in all compounds, consistent with density functional theory calculations that reveal better Fermi surfacemore »« less

Spin anisotropy due to spin-orbit coupling in optimally hole-doped Ba_0.67K_0.33Fe₂As₂

Journal Article Song, Yu ; Man, Haoran ; Zhang, Rui ; ... - Physical Review B

Here, we use polarized inelastic neutron scattering to study the temperature and energy dependence of spin space anisotropies in the optimally-hole-doped iron pnictide Ba_0.67K_0.33Fe₂As₂ (T_c = 38 K). In the superconducting state, while the high-energy part of the magnetic spectrum is nearly isotropic, the low-energy part displays a pronounced anisotropy, manifested by a c -axis polarized resonance. We also observe that the spin anisotropy in superconducting Ba_0.67K_0.33Fe₂As₂ extends to higher energies compared with electron-doped BaFe_2-xTM_xAs₂ (TM = Co, Ni) and isovalent-doped BaFe₂As_1.4P_0.6, suggesting a connection between T_c and the energy scale of the spin anisotropy.
