Title: Coexistence of superconductivity and magnetism in CaK(Fe_1–xNi_x)₄As₄ as probed by ⁵⁷Fe Mössbauer spectroscopy

Abstract

Temperature dependent ⁵⁷Fe Mössbauer spectroscopy and specific heat measurements for CaK(Fe_1–xNi_x)₄As₄ with x = 0, 0.017, 0.033, and 0.049 are presented. No magnetic hyperfine field (i.e., no static magnetic order) down to 5.5 K was detected for x = 0 and 0.017 in agreement with the absence of any additional feature below superconducting transition temperature T_c in the specific heat data. The evolution of magnetic hyperfine field with temperature was studied for x = 0.033 and 0.049. The long-range magnetic order in these two compounds coexists with superconductivity. The magnetic hyperfine field B_hf (ordered magnetic moment) below T_c in CaK(Fe_0.967Ni_0.033)₄As₄ is continuously suppressed with the developing superconducting order parameter. The B_hf(T) data for CaK(Fe_0.967Ni_0.033)₄As₄ and CaK(Fe_0.951Ni_0.049)₄As₄ can be described reasonably well by Machida's model for coexistence of itinerant spin density wave magnetism and superconductivity. Furthermore, we demonstrate directly that superconductivity suppresses the spin density wave order parameter if the conditions are right, in agreement with the theoretical analysis.

Superconductivity and phase diagrams of CaK(Fe_1-xMn_x)₄As₄ single crystals

Journal Article Xu, M. ; Schmidt, J. ; Gati, E. ; ... - Physical Review. B

In order to study the effects of Mn substitution on the superconducting and magnetic ground state of CaKFe₄As₄ (T_c = 35 K), members of the CaK (Fe_1–xMn_x)₄As₄ series have been synthesized by high-temperature solution growth in single-crystalline form and characterized by elemental analysis, thermodynamic, and transport measurements. These measurements show that the superconducting transition temperature decreases monotonically and is finally suppressed below 1.8 K as x is increased from 0 to 0.036. For x values greater than 0.016, signatures of a magnetic transition can be detected in both thermodynamic and transport measurements in which kinklike features allow for the determination of the transition temperature T* that increases as Mn substitution increases. Here, a temperature-composition (T–x) phase diagram is constructed, revealing a half-dome of superconductivity with the magnetic transition temperature T* appearing near 26 K for x ~ 0.017 and rising slowly up to 33 K for x ~ 0.036. In addition to the creation of the T–x phase diagram for CaK(Fe_1–xMn_x)₄As₄, specific-heat data are used to track the jump in specific heat at T_c; the CaK(Fe_1–xMn_x)₄As₄ data do not follow the scaling of ΔC_p withmore »« less

Superconductivity and magnetic and transport properties of single-crystalline CaK ( Fe 1 – x Cr x ) 4 As 4

Journal Article Xu, Mingyu ; Schmidt, J. ; Tanatar, M. A. ; ... - Physical Review. B

Members of the CaK (Fe_1–xCr_x)₄ As₄ series have been synthesized by high-temperature solution growth in single-crystalline form and characterized by x-ray diffraction, elemental analysis, and magnetic and transport measurements. The effects of Cr substitution on the superconducting and magnetic ground states of CaKFe₄ As₄ (T_c = 35 K) have been studied. These measurements show that the superconducting transition temperature decreases monotonically and is finally suppressed below 1.8 K as x is increased from 0 to 0.038. For x-values greater than 0.012, signatures of a magnetic transition can be detected in magnetic measurements with the associated features in the transport measurements becoming detectable for x ≥ 0.038. The magnetic transition temperature increases in a roughly linear manner as Cr substitution increases. A temperature-composition (T – x) phase diagram is constructed, revealing a half-dome of superconductivity with the magnetic transition temperature, T*, appearing near 22 K for x ~ 0.017 and rising slowly up to 60 K for x ~ 0.077. The T – x phase diagrams for CaK (Fe_1–xT_x)₄ As₄ for T = Cr and Mn are essentially the same despite the nominally different band filling; this is in marked contrast to T = Co and Ni series for which the T – x diagrams scale by a factor of 2, consistent with the different changes in band filling Co and Ni would produce when replacing Fe. Superconductivity of CaK (Fe_1–xCr_x)₄ As₄ is also studied as a function of magnetic field. A clear change inmore »« less

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). The low-temperature variation of London penetration depth ismore »« less
