Multiple ordered phases in the filled skutterudite compound PrOsAs
W. M. Yuhasz, N. P. Butch, T. A. Sayles +10
Magnetization, specific heat, and electrical resistivity measurements were made on single crystals of the filled skutterudite compound PrOsAs. Specific heat measuremen…
Double superconducting transition and low-temperature specific heat study of Pr(OsRu)Sb
N. A. Frederick, T. A. Sayles, S. K. Kim +1
The double superconducting transition in PrOsSb, first observed in specific heat measurements of single crystal samples, is the subject of an in-depth study. The…
Universal Critical Dynamic Form of the Vortex-Lattice Melting Line
B. J. Taylor, M. B. Maple
A modified form of the vortex-lattice melting line is arrived at by incorporating the effects of critical behavior at the melting transition. Beginning with the universal form esta…
Susceptibility inhomogeneity and non-Fermi liquid behavior in UCu_{5-x}Pt_x
D. E. MacLaughlin, M. S. Rose, O. O. Bernal +4
Transverse-field muSR shifts and relaxation rates have been measured in the non-Fermi liquid (NFL) alloy system UCu_{5-x}Pt_x, x = 1.0, 1.5, and 2.5. At low temperatures the fracti…
Effect of annealing on glassy dynamics and non-Fermi liquid behavior in UCu_4Pd
D. E. MacLaughlin, M. S. Rose, J. E. Anderson +6
Longitudinal-field muon spin relaxation (LF-muSR) experiments have been performed in unannealed and annealed samples of the heavy-fermion compound UCu_4Pd to study the effect of di…
Optical study of interactions in a d-electron Kondo lattice with ferromagnetism
K. S. Burch, A. Schafgans, N. P. Butch +5
We report on a comprehensive optical, transport and thermodynamic study of the Zintl compound YbMnSb, demonstrating that it is the first ferromagnetic Kondo lattice c…
Transport properties of moderately disordered UCuPd
A. Otop, S. Süllow, M. B. Maple +4
We present a detailed study on the (magneto)transport properties of as-cast and heat treated material UCuPd. We find a pronounced sample dependence of the resistivity of as…
Penetration depth, symmetry breaking, and gap nodes in superconducting PrOs4Sb12
Lei Shu, D. E. MacLaughlin, R. H. Heffner +9
Transverse-field muon spin relaxation rates in single crystals of the heavy-fermion superconductor PrOs4Sb12 (Tc = 1.85 K) are nearly constant in the vortex state for temperatures…
Quantum Critical Scaling and origin of Non-Fermi-Liquid behavior in ScUPd
Stephen D. Wilson, Pengcheng Dai, D. T. Adroja +5
We use inelastic neutron scattering to study magnetic excitations of ScUPd for U concentrations (, 0.35) near the spin glass quantum critical point (QCP).…
