Chemical pressure tuning of URuSi via isoelectronic substitution of Ru with Fe
Pinaki Das, N. Kanchanavatee, J. S. Helton +8
We have used specific heat and neutron diffraction measurements on single crystals of URuFeSi for Fe concentrations 0.7 to establish that chemical substi…
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…
Pressure studies of the quantum critical alloy Ce(0.93)Yb(0.07)CoIn5
Y. P. Singh, D. J. Haney, Xinyi Huang +4
Here we present our experimental and theoretical study of the effects of pressure on the transport properties of the heavy-fermion alloy Ce(1-x)Yb(x)CoIn5 with x~0.07. We specifica…
Non-Fermi Liquid Behavior Close to a Quantum Critical Point in a Ferromagnetic State without Local Moments
E. Svanidze, L. Liu, B. Frandsen +12
A quantum critical point (QCP) occurs upon chemical doping of the weak itinerant ferromagnet Sc_{3.1}In. Remarkable for a system with no local moments, the QCP is accompanied by no…
Landau Renormalizations of Superfluid density in Heavy Fermion Superconductor CeCoIn5
Lei Shu, D. E. MacLaughlin, C. M. Varma +5
The formation of heavy fermion bands can occur by means of the conversion of a periodic array of local moments into itinerant electrons via the Kondo effect and the huge consequent…
Effect of yttrium substitution on the superconducting properties of the system LaYOFBiS
I. Jeon, D. Yazici, B. D. White +2
We present the effect of yttrium substitution on superconductivity in the LaYOFBiS system. Polycrystalline samples with nomina…
