Title: Is ${BaCr}_{2} {As}_{2}$ symmetrical to ${BaFe}_{2} {As}_{2}$ with respect to half $3 d$ shell filling?

Abstract

We have performed an angle-resolved photoemission spectroscopy study of BaCr₂As₂, which has the same crystal structure as BaFe2As2, a parent compound BaFe₂As₂ of Fe-based superconductors. We determine the Fermi surface of this material and its band dispersion down to 5 eV below the Fermi level. Very moderate band renormalization (1.35) is observed for only two bands. We attribute this small renormalization to enhanced direct exchange as compared to Fe in BaFe₂As₂, and to a larger contribution of the eg orbitals in the composition of the bands forming the Fermi surface.

Interplay of lattice, electronic, and spin degrees of freedom in detwinned ${BaFe}_{2} {As}_{2}$ : A Raman scattering study

Journal Article Baum, A. ; Li, Ying ; Tomić, M. ; ... - Physical Review. B

We report results of Raman scattering experiments on twin-free BaFe₂ As₂ with the main focus placed on understanding the influence of electronic and spin degrees of freedom on the lattice dynamics. In particular, we scrutinize the Eg modes and the As A_1g mode. Each of the two Eg phonons in the tetragonal phase is observed to split into a B_2g and a B_3g mode upon entering the orthorhombic stripe-magnetic phase. The splitting amounts to approximately 10 cm^-1 and less than 5 cm^-1 for the low- and the high-energy E_g mode, respectively. The detailed study of the fully symmetric As modemore »« less

Superconducting gap evolution in overdoped ${BaFe}_{2} {({As}_{1 - x} P_{x})}_{2}$ single crystals through nanocalorimetry

Journal Article Campanini, D. ; Diao, Z. ; Fang, L. ; ... - Physical Review. B, Condensed Matter and Materials Physics

We report on specific heat measurements on clean overdoped BaFe₂(As_1-xP_x)₂ single crystals performed with a high resolution membrane-based nanocalorimeter. A nonzero residual electronic specific heat coefficient at zero temperature γ_r = C/T |_{T→ 0} is seen for all doping compositions, indicating a considerable fraction of the Fermi surface ungapped or having very deep minima. The remaining superconducting electronic specific heat is analyzed through a two-band s-wave alpha model in order to investigate the gap structure. Close to optimal doping we detect a single zero-temperature gap of Δ₀ ~ 5.3 meV, corresponding to Δ₀/k_BT_c ~ 2.2. Increasing the phosphorus concentration x, the main gap reduces till a value of Δ₀ ~ 1.9 meV for x = 0.55 and a second weaker gap becomes evident. From the magnetic field effect on γ_r, all samples however show similar behavior γ_r(H)more »« less

Recent nuclear magnetic resonance (NMR) measurements revealed the coexistence of stripe-type antiferromagnetic (AFM) and ferromagnetic (FM) spin correlations in both the hole- and electron-doped BaFe ₂ As ₂ families of iron-pnictide superconductors by a Korringa ratio analysis. Motivated by the NMR work, we investigate the possible existence of FM fluctuations in another iron-pnictide superconducting family, Ca ( Fe _{1 - x}Co _x ) ₂ As ₂ . We reanalyzed our previously reported data in terms of the Korringa ratio and found clear evidence for the coexistence of stripe-type AFM and FM spin correlations in the electron-doped CaFe ₂ Asmore »« less

Journal Article Khan, S. N. ; Alam, Aftab ; Johnson, Duane D. - Physical Review. B, Condensed Matter and Materials Physics

BaFe₂As₂ with transition-metal doping exhibits a variety of rich phenomena from the coupling of structure, magnetism, and superconductivity. Using density functional theory, we systematically compare the Fermi surfaces (FSs), formation energies (ΔE_f), and densities of states (DOSs) of electron-doped Ba(Fe_1-xMx)₂As₂ with M={Co,Ni,Cu,Zn} in tetragonal (I4/mmm) and orthorhombic (Fmmm) structures in nonmagnetic, antiferromagnetic, and paramagnetic (disordered local moment) states. We explain changes to the phase stability (ΔE_f) and Fermi surfaces (and nesting) due to chemical and magnetic disorder. We compare our results to observed/assessed properties and contrast alloy theory with the results expected from the rigid-band model. Finally, with alloying, themore »« less

Magnetoresistance Scaling Reveals Symmetries of the Strongly Correlated Dynamics in ${BaFe}_{2} ({As}_{1 - x} P_{x})_{2}$

Journal Article Hayes, Ian M. ; Hao, Zeyu ; Maksimovic, Nikola ; ... - Physical Review Letters

The phenomenon of T-linear resistivity commonly observed in a number of strange metals has been widely seen as evidence for the breakdown of the quasiparticle picture of metals. This study shows that a recently discovered H/T scaling relationship in the magnetoresistance of the strange metal BaFe₂(As_1-xP_x)₂ is independent of the relative orientations of current and magnetic field. Rather, its magnitude and form depend only on the orientation of the magnetic field with respect to a single crystallographic axis: the direction perpendicular to the magnetic iron layers. In this work, this finding suggests that the magnetotransport scaling does not originate frommore »« less
