Title: Crossover and coexistence of superconductivity and antiferromagnetism in the filled-skutterudite system $\Pr_{1 - x} {Eu}_{x} {Pt}_{4} {Ge}_{12}$

Abstract

The superconducting and normal-state properties of the filled-skutterudite system Pr_1-xEu_xPt₄Ge₁₂ were studied. Polycrystalline samples were investigated via x-ray diffraction, electrical resistivity, magnetic susceptibility, and specific-heat measurements. Upon Eu substitution, we observed a crossover from superconducting to antiferromagnetic states with a region where both states coexist. Here, in the superconducting region, the specific-heat data exhibit a change of temperature dependence, suggesting an evolution from a nodal to a nodeless superconducting energy gap or a suppression of multiband superconductivity. This change is relatively slower than those reported for different substituent ions, suggesting that paramagnetic impurities have a weaker pair-breaking effect on unconventional superconductivity in PrPt₄Ge₁₂. In the normal state, an evolution from Fermi-liquid to non-Fermi-liquid behavior was observed, accompanied by the coexistence of superconductivity and antiferromagnetism, suggesting that the underlying electronic structure is primarily responsible for the complex physical phenomena found in this system.

Investigation of superconducting and normal-state properties of the filled-skutterudite system ${PrPt}_{4} {Ge}_{12 - x} {Sb}_{x}$

Journal Article Jeon, I. ; Huang, K. ; Yazici, D. ; ... - Physical Review B

We report a study of the superconducting and normal-state properties of the filled-skutterudite system PrPt₄Ge_{12 - x} Sb_x. Polycrystalline samples with Sb concentrations up to x = 5 were synthesized and investigated by means of x-ray diffraction, electrical resistivity, magnetic susceptibility, and specific heat measurements. We observed a suppression of superconductivity with increasing Sb substitution up to x = 4 , above which no signature of superconductivity was observed down to 140 mK. The Sommerfeld coefficient, γ , of superconducting specimens decreases with increasing x up to x = 3 , suggesting that superconductivity may depend on the density ofmore »« less

Electrical resistivity, magnetization, and specific heat measurements were performed on polycrystalline samples of the filled-skutterudite systems La_1-xM_xPt₄Ge₁₂ (M = Ce, Th). Superconductivity in LaPt4Ge12 was quickly suppressed with Ce substitution and no evidence for superconductivity was found down to 1.1 K for x > 0.2. Temperature-dependent specific heat data at low temperatures for La_1-xCe_xPt₄Ge₁₂ show a change from power-law to exponential behavior, which may be an indication for multi-band superconductivity in LaPt₄Ge₁₂. A similar crossover was observed in the Pr_1-xCe_xPt₄Ge₁₂ system. However, the suppression rates of the superconducting transition temperatures, T_c(x), in the two systems are quite disparate, indicating amore »« less

Journal Article Singh, Y. P. ; Adhikari, R. B. ; Zhang, S. ; ... - Physical Review B

Studies of superconductivity in multiband correlated electronic systems have become one of the central topics in condensed-matter and materials physics. In this paper, we present the results of thermodynamic measurements on the superconducting filled skutterudite system Pr_1-xCe_xPt₄Ge₁₂ ( 0 ≤ x ≤ 0.2 ) to investigate how substitution of Ce at Pr sites affects superconductivity. We find that an increase in Ce concentration leads to a suppression of the superconducting transition temperature from T c ~ 7.9 K for x = 0 to T c ~ 0.6 K for x = 0.14 .

Europium mixed-valence, long-range magnetic order, and dynamic magnetic response in ${EuCu}_{2} {(Si}_{x} {Ge}_{1 - x})_{2}$

Journal Article Nemkovski, Krill S. ; Kozlenko, D. P. ; Alekseev, Pavel A. ; ... - Physical Review B

In mixed-valence or heavy-fermion systems, the hybridization between local f orbitals and conduction band states can cause the suppression of long-range magnetic order, which competes with strong spin uctuations. Ce- and Yb-based systems have been found to exhibit fascinating physical properties (heavy-fermion superconductivity, non-Fermi-liquid states, etc.) when tuned to the vicinity of magnetic quantum critical points by use of various external control parameters (temperature, magnetic eld, chemical composition). Recently, similar effects (mixed-valence, Kondo uctuations, heavy Fermi liquid) have been reported to exist in some Eu-based compounds. Unlike Ce (Yb), Eu has a multiple electron (hole) occupancy of its 4f shell,more »« less

High-pressure effects on nonfluorinated ${BiS}_{2}$ -based superconductors ${La}_{1 - x} M_{x} {OBiS}_{2}$ ( $M = Ti$ and Th)

Journal Article Fang, Y. ; Yazici, D. ; Jeon, I. ; ... - Physical Review B

Layered LnOBiS₂ (where Ln represents a lanthanide element) compounds with Ln = La, Ce, Pr, Nd, and Yb can be rendered conducting and superconducting via two routes, substitution of F for O or the tetravalent ions Ti, Zr, Hf, and Th for trivalent Ln ions. Electrical resistivity measurements on nonfluorinated La_0.80Ti_0.20OBiS₂ and La_0.85Th_0.15OBiS₂ superconductors were performed between ~1.5 and 300 K and under pressure up to 2.4 GPa. For both compounds, the superconducting transition temperature T_c, which is ~2.9K at ambient pressure, gradually increases with pressure to 3.2–3.7 K at ~1GPa, above which it is suppressed and the superconducting transitionsmore »« less
