“…In the vicinity of the putative structural quantum critical point where T * extrapolates to 0 K, μSR [22] and specific heat [5] detected a strongly enhanced electron-phonon coupling strength, indicated by the enhancement in 2 (0)/k B T c and C/γ T c beyond the BCS weak-coupling values [35][36][37], where (0) is the size of the gap, C is the specific heat jump at T c and γ is the Sommerfeld coefficient.

“…[23,24]. It is a superconductor with a T c of ∼2.7 K [24,25]. Incidentally, La 3 Co 4 Sn 13 has been shown to exhibit a feature at T * ∼ 152 K, which is detectable in the electrical resistivity, the heat capacity, the NMR Knight shift, and the nuclear spin-lattice relaxation rate [10,11].…”

Second-order structural transition in the superconductorLa3Co4Sn13

The quasiskutterudite superconductor La 3 Co 4 Sn 13 undergoes a phase transition at T * = 152 K. By measuring the temperature dependence of heat capacity, electrical resistivity, and the superlattice reflection intensity using x rays, we explore the character of the phase transition at T * . Our lattice dynamic calculations found imaginary phonon frequencies around the M point when the high-temperature structure is used in the calculations, indicating that the structure is unstable at the zero-temperature limit. The combined experimental and computational results establish that T * is associated with a second-order structural transition with q = (0.5,0.5,0) (or the M point). Further electronic band structure calculations reveal Fermi surface sheets with low-curvature segments, which allow us to draw qualitative comparison with both Sr 3 Ir 4 Sn 13 and Sr 3 Rh 4 Sn 13 in which similar physics has been discussed recently.

“…The structures at T = 300 K, 120 K and 12 K were solved by Rietveld analysis and refined using the FULPROF package. By comparing the interatomic distances Sn1-Sn2, Ce-Sn2, and Co-Sn2 in Ce 3 Co 4 Sn 13 , we observe that the distances Sn1(Sn2) 12 , Ce(Sn2) 4 , and Ce(Sn2) 8 are evidently temperature dependent, which suggests that the structure becomes locally distorted at T = 120 K and 12 K with respect to the structure at room temperature.

We present an investigation of the magnetic, thermodynamic, and electric transport properties, and the electronic structure of the strongly correlated compounds Ce3Rh4Sn13 and Ce3Co4Sn13. The main goal of this report is to compare the physical properties of both compounds and to explain the abnormal electrical resistivity behavior in Ce3Co4Sn13 above ∼ 160 K, which has not been observed in Ce3Rh4Sn13. We suggest that a possible local distortion of the trigonal Sn2 prisms around Co occurs in Ce3Co4Sn13 below ∼ 160 K, which could change the electronic structure near the Fermi level, and as a consequence, explain the metallic behavior visible in the resistivity above this temperature. We determined experimentally the hybridization energy ∆ between the f -electron and conduction-electron states for both compounds and its influence on the different ρ(T ) behaviors under pressure. The complimentary experimental data allowed us to explain the semimetallic properties of both compounds and the transition between semimetallic and metallic behavior in Ce3Co4Sn13, which is not observed for Ce3Rh4Sn13.

“…For example, both Ce 3 Co 4 Sn 13 and Ce 3 Rh 4 Sn 13 show heavy fermion behavior at low temperatures [17,18]. In these compounds, competition between magnetic orders and collective hybridization of localized f electrons with background conduction electrons may lead to a magnetic quantum phase transition at zero temperature.…”

We report the crystal growth of a new compound, Yb 3 Os 4 Ge 13 , by using a Bi-flux method.X-ray diffraction measurement shows that it crystallizes in the quasi-skutterudite-type caged structure with a cubic space group of . Magnetic measurements reveal almost fully localized Yb f-moments above 120 K. The resistivity exhibits a crossover from metallic to insulating behavior with a logarithmic increase below ~ 40 K. The specific heat coefficient shows a rapid upturn below ~5 K and exceeds 2 J mol -1 K -2 at 2 K. Our experimental analysis and electronic band structure calculations demonstrate that Yb 3 Os 4 Ge 13 exhibits the Kondo effect due to strong hybridization of the localized Yb f-moments with the p-electrons of the surrounding Ge-cages.
