Title: Structural and antiferromagnetic properties of $Ba ({Fe}_{1 - x - y} {Co}_{x} {Rh}_{y})_{2} {As}_{2}$ compounds

Abstract

Here, we present a systematic investigation of the electrical, structural, and antiferromagnetic properties for the series of Ba(Fe_1-x-yCoxRh_y)₂As₂ compounds with fixed x≈0.027 and 0≤y≤0.035. We compare our results for the Co-Rh doped Ba(Fe_1-x-yCo_xRh_y)₂As₂ compounds with the Co doped Ba(Fe_1-xCo_x)₂As₂ compounds. We demonstrate that the electrical, structural, antiferromagnetic, and superconducting properties of the Co-Rh doped compounds are similar to the properties of the Co doped compounds. We find that the overall behaviors of Ba(Fe_1-x-yCo_xRh_y)₂As₂ and Ba(Fe_1-xCo_x)₂As₂ compounds are very similar when the total number of extra electrons per Fe/TM (TM=transition metal) site is considered, which is consistent with the rigid band model. Despite the similarity, we find that the details of the transitions, for example, the temperature difference between the structural and antiferromagnetic transition temperatures and the incommensurability of the antiferromangetic peaks, are different between Ba(Fe_1-x-yCo_xRh_y)₂As₂ and Ba(Fe_1-xCo_x)₂As₂ compounds.

Weak ferromagnetism of $Cu_{x} Fe_{1 + y} As$ and its evolution with Co doping

Journal Article Qian, Bin ; Hu, Jin ; Liu, Jinyu ; ... - Physical Review. B, Condensed Matter and Materials Physics

We have investigated electronic and magnetic properties of iron pnictide Cu_xFe_1+yAs, which is isostructural to iron pnictide superconductors LiFeAs and NaFeAs, using polycrystalline and single crystal samples. Here, we found that Cu_xFe_1+yAs is characterized by strong electron correlations and shows weak ferromagnetic behavior with the Curie temperature T_c ~ 42 K, in contrast with the superconductivity in LiFeAs and NaFeAs. Its electronic transport properties exhibit quasi-two-dimensional characteristics: while the in-plane resistivity follows quadratic temperature dependence for T < 10K, the c-axis resistivity shows nonmetal-to-metal crossover near 20 K. In addition, we have studied Co doping effect on Cu_xFe_1+yAs and foundmore »« less

Strontium doping transforms manganites of type La _{1 - x} Sr _x Mn O ₃ from an insulating antiferromagnet ( x = 0 ) to a metallic ferromagnet ( x > 0.16 ) due to the induced charge carriers (holes).

Robust $s_{\pm}$ pairing in $CaK {({Fe}_{1 - x} {Ni}_{x})}_{4} {As}_{4}$ ( $x = 0$ and 0.05) from the response to electron irradiation

Journal Article Teknowijoyo, S. ; Cho, K. ; Konczykowski, M. ; ... - Physical Review B

Here, controlled pointlike disorder introduced by 2.5-MeV electron irradiation was used to probe the superconducting state of single crystals of CaK(Fe_1–xNi_x)₄As₄ superconductor at x = 0 and 0.05 doping levels. Both compositions show an increase of the residual resistivity and a decrease of the superconducting transition temperature, T_c, at the rate of dT_c/dρ(T_c) ≈ 0.19 K/(μΩcm) for x = 0 and 0.38 K/(μΩcm) for x = 0.05, respectively. In the Ni-doped compound (x = 0.05), the coexisting spin-vortex crystal (SVC) magnetic phase is suppressed at the rate of dT_N/dρ(T_N) ≈ 0.16 K/(μΩcm).
