Title: Resolution of the discrepancy between the variation of the physical properties of Ce_1-xYb_xCoIn₅ single crystals and thin films with Yb composition

Abstract

The extraordinary electronic phenomena including an Yb valence transition, a change in Fermi surface topology, and suppression of the heavy fermion quantum critical field at a nominal concentration x≈0.2 have been found in the Ce_1-xYb_xCoIn₅ system. These phenomena have no discernable effect on the unconventional superconductivity and normal-state non-Fermi liquid behaviour that occur over a broad range of x up to ~0.8. However, the variation of the coherence temperature T* and the superconducting critical temperature T_c with nominal Yb concentration x for bulk single crystals is much weaker than that of thin films. To determine whether differences in the actual Yb concentration of bulk single crystals and thin film samples might be responsible for these discrepancies, we employed Vegard’s law and the spectroscopically determined values of the valences of Ce and Yb as a function of x to determine the actual composition x_act of bulk single crystals. This analysis is supported by energy-dispersive X-ray spectroscopy, wavelength-dispersive X-ray spectroscopy, and transmission X-ray absorption edge spectroscopy measurements. The actual composition x_act is found to be about one-third of the nominal concentration x up to x~0.5, and resolves the discrepancy between the variation of the physical properties of Ce_1-xYb_xCoIn₅ single crystals and thinmore » films with Yb concentration.« less

Insensitivity of the pressure dependences of characteristic energy scales in Ce_1–xR_xCoIn₅ (R=Yb,Y,Gd) to the electronic configuration of the rare-earth ion

Journal Article White, B. D. ; Hamlin, J. J. ; Huang, K. ; ... - Physical Review. B, Condensed Matter and Materials Physics

Cooperative Ce and Yb valence fluctuations have recently been proposed as the mechanism responsible for stabilizing correlated electron phenomena in Ce₁₋_xYbxCoIn₅ over an unexpectedly large range of concentrations. In order to better understand the origins and character of this stability, we have measured the effect of applied pressure on relevant energy scales such as the superconducting critical (T_c) and Kondo-lattice coherence (T*) temperatures of Ce₁₋_xR_xCoIn₅ with R=Yb, Y, and Gd. Electrical resistivity measurements were performed under applied pressure on samples doped with intermediate-valent Yb and stable-valent Gd and Y, and the responses of Tc and T* to increased pressure inmore »« less

Universal heat conduction in Ce_1-xYb_xCoIn₅: Evidence for robust nodal d-wave superconducting gap

Journal Article Xu, Y. ; Petrovic, C. ; Dong, J. K. ; ... - Physical Review B

In the heavy-fermion superconductor Ce_1-xYb_xCoIn₅, Yb doping was reported to cause a possible change from nodal d-wave superconductivity to a fully gapped d-wave molecular superfluid of composite pairs near x ≈ 0.07 (nominal value x_nom = 0.2). Here we present systematic thermal conductivity measurements on Ce_1-xYb_xCoIn₅ (x = 0.013, 0.084, and 0.163) single crystals. The observed finite residual linear term κ₀/T is insensitive to Yb doping, verifying the universal heat conduction of the nodal d-wave superconducting gap in Ce_1-xYb_xCoIn₅. Similar universal heat conduction is also observed in the CeCo(In_1–yCd_y)₅ system. Furthermore, these results reveal a robust nodal d-wave gap inmore » CeCoIn₅ upon Yb or Cd doping.« less

Robust upward dispersion of the neutron spin resonance in the heavy fermion superconductor Ce_1–xYb_xCoIn₅

Journal Article Song, Yu ; Van Dyke, John ; Lum, I. K. ; ... - Nature Communications

Here, the neutron spin resonance is a collective magnetic excitation that appears in copper oxide, iron pnictide, and heavy fermion unconventional superconductors. Although the resonance is commonly associated with a spin-exciton due to the d(s^±)-wave symmetry of the superconducting order parameter, it has also been proposed to be a magnon-like excitation appearing in the superconducting state. Here we use inelastic neutron scattering to demonstrate that the resonance in the heavy fermion superconductor Ce_1–xYb_xCoIn₅ with x=0,0.05,0.3 has a ring-like upward dispersion that is robust against Yb-doping. By comparing our experimental data with random phase approximation calculation using the electronic structure andmore »« less

Tuning the magnetic ground state of ${Ce}_{1 - x} {Yb}_{x} {RhIn}_{5}$ by Yb valence fluctuations

Journal Article Jang, S. ; Pouse, N. ; Keiber, T. ; ... - Physical Review B

We characterize the properties of Ce_1–x Yb_x RhIn₅ single crystals with 0 ≤ x ≤ 1 using measurements of powder x-ray diffraction, energy dispersive x-ray spectroscopy, electrical resistivity, magnetic susceptibility, specific heat, x-ray absorption near edge structure (XANES), and neutron diffraction. Here, the Yb valence v Yb , calculated from the magnetic susceptibility and measured using XANES, decreases from 3+ at x = 0 to ~2.1+ at x_act = 0.2 , where x_act is the measured Yb concentration. A transition from incommensurate to commensurate antiferromagnetism is observed in neutron diffraction measurements along Q = (0.5, 0.5, l) between 0.2 ≤more »« less

Thesis/Dissertation Ahn, Kyunghan

The family of R₅Si_xGe_4-x alloys demonstrates a variety of unique physical phenomena related to magneto-structural transitions associated with reversible breaking and reforming of specific bonds that can be controlled by numerous external parameters such as chemical composition, magnetic field, temperature, and pressure. Therefore, R₅Si_xGe_4-x systems have been extensively studied to uncover the mechanism of the extraordinary magneto-responsive properties including the giant magnetoresistance (GMR) and colossal magnetostriction, as well as giant magnetocaloric effect (GMCE). Until now, more than a half of possible R₅Si_xGe_4-x pseudobinary systems have been completely or partially investigated with respect to their crystallography and phase relationships (R =more »« less
