Renormalizations in unconventional superconducting states of CeYbCoIn
Zhaofeng Ding, Jian Zhang, Cheng Tan +7
We have measured the superconducting penetration depth~ in the heavy-fermion/intermediate-valent superconducting alloy series~CeYbCoIn using transverse-field…
Robust Upward Dispersion of the Neutron Spin Resonance in the Heavy Fermion Superconductor CeYbCoIn
Yu Song, John Van Dyke, I. K. Lum +10
The neutron spin resonance is a collective magnetic excitation that appears in copper oxide, iron pnictide, and heavy fermion unconventional superconductors. Although the resonance…
Universal Heat Conduction in Ce1-xYbxCoIn5: Evidence for Robust Nodal d-wave Superconducting Gap
Y. Xu, J. K. Dong, L. I. Lum +9
In heavy-fermion superconductor CeYbCoIn system, Yb doping was reported to cause a possible change from nodal -wave superconductivity to a fully gapped -wave…
Quantum criticality and superconducting pairing in Ce(1-x)Yb(x)CoIn5 alloys
Y. P. Singh, D. J. Haney, I. K. Lum +4
In this paper we review some of our recent experimental and theoretical results on transport and thermodynamic properties of heavy-fermion alloys Ce(1-x)Yb(x)CoIn5. Charge transpor…
Resolution of the discrepancy between the variation of the physical properties of Ce1-xYbxCoIn5 single crystals and thin films with Yb composition
S. Jang, B. D. White, I. K. Lum +10
Measurements of physical properties show that Yb enters the single crystals systematically and in registry with the nominal Yb concentration x of the starting material dissolved in…
Evolution of the superconducting energy gap structure concomitant with Fermi surface reconstruction in the heavy-fermion superconductor CeCoIn5
Hyunsoo Kim, M. A. Tanatar, R. Flint +6
The London penetration depth, was measured in single crystals of CeCoIn, =La, Nd and Yb down to 50~mK (50) using a tunnel-diode resonator. In t…
Probing the superconductivity of PrPt4Ge12 through Ce substitution
K. Huang, L. Shu, I. K. Lum +8
We report measurements of electrical resistivity, magnetic susceptibility, specific heat, and thermoelectric power on the system Pr1-xCexPt4Ge12. Superconductivity is suppressed wi…
From local moment to mixed-valence regime in Ce(1-x)Yb(x)CoIn5 alloys
Y. P. Singh, D. J. Haney, X. Y. Huang +5
We investigated the onset of the many-body coherence in the f-orbital single crystalline alloys Ce(1-x)Yb(x)CoIn5 through thermodynamic and magneto-transport measurements. Our stud…
Superconductivity induced by electron doping in the system La1-xMxOBiS2 (M = Ti, Zr, Hf, Th)
D. Yazici, K. Huang, B. D. White +7
We report a strategy to induce superconductivity in the BiS-based compound LaOBiS. Instead of substituting F for O, we increase the charge-carrier density (electron dope) v…
Search for pressure induced superconductivity in CeFeAsO and CeFePO iron pnictides
Diego A. Zocco, Ryan E. Baumbach, James J. Hamlin +11
The CeFeAsO and CeFePO iron pnictide compounds were studied via electrical transport measurements under high-pressure. In CeFeAsO polycrystals, the magnetic phases involving the Fe…
