Title: Superconducting and normal state properties of the systems ${La}_{1 - x} M_{x} {Pt}_{4} {Ge}_{12}$ ( $M = Ce, Th$ )

Abstract

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 a difference in the nature of superconductivity, which is conventional in LaPt₄Ge₁₂ and unconventional in PrPt₄Ge₁₂. In comparison, a nearly linear and smooth evolution of T_c with increasing Th was observed in the La_1-xTh_xPt₄Ge₁₂ system, with no change of the superconducting energy gap in the temperature dependence of the specific heat, suggesting similar types of superconductivity in both the LaPt₄Ge₁₂ and ThPt₄Ge₁₂ compounds.

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

Journal Article Jeon, I. ; Ran, S. ; Breindel, A. J. ; ... - Physical Review B

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 unconventionalmore »« less

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

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.

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 .
